Basic Storage of Nendoroids | 3 Important Points to Prevent Deterioration

The important points to keep in mind for nendoroid storage are "temperature and humidity management," "UV measures," and "dust prevention." By managing these appropriately, you can significantly prevent the deterioration of the figures.

Nendoroids are mainly made of PVC (polyvinyl chloride) and ABS resin, which are materials that are easily affected by environmental factors. Especially when exposed to high temperatures, high humidity, or direct sunlight, chemical changes in the materials can progress, leading to deterioration such as discoloration, stickiness, and deformation. Conversely, if stored in an appropriate environment, they can maintain their beautiful condition for a long time.

When setting up the storage environment, start by understanding the temperature and humidity of the storage location. Next, choose a place that is not exposed to direct sunlight, and finally, prepare a case to protect against dust. By keeping these three points in mind, you will have completed the basics of nendoroid storage.

Why Do Nendoroids Deteriorate? Understanding Material Properties

The main material of nendoroids, PVC (polyvinyl chloride), is a material that excels in flexibility and processability, but it has the characteristic of being weak to heat and UV rays. PVC contains plasticizers, which are additives that maintain softness, and when exposed to high temperatures, these plasticizers can seep to the surface, causing "stickiness."

Additionally, when exposed to UV rays, the molecular structure changes, leading to fading and yellowing. This is not only due to the deterioration of the paint but also due to the alteration of the material itself. ABS resin parts similarly become harder and more brittle when exposed to UV rays and high temperatures, increasing the risk of cracking.

Furthermore, rapid temperature changes and high humidity environments can cause repeated expansion and contraction of the material, leading to fine cracks, and the risk of mold growth due to moisture also increases. Understanding the properties of the materials clarifies why an appropriate storage environment is necessary.

Three Major Factors to Be Careful of in the Storage Environment

The three major factors to pay particular attention to in nendoroid storage are temperature and humidity, UV rays, and dust. These are the main causes of deterioration, so it is essential to prioritize measures against them.

Temperature and Humidity: The ideal storage environment is a temperature of 18-25℃ and humidity of 40-60%. In high temperature and humidity, stickiness and mold can occur, while extreme dryness can cause the material to harden and become brittle. It is important to constantly monitor the indoor environment, which can fluctuate with the seasons, using a thermometer and hygrometer.

UV Rays: UV rays emitted from direct sunlight and fluorescent lights are the main cause of fading and discoloration. It is essential to take measures such as not placing them near windows, using UV-cut cases, and utilizing blackout curtains. Special care is needed for nendoroids that are white or light-colored, as they are prone to yellowing.

Dust: Dust not only detracts from appearance but can also absorb moisture, becoming a breeding ground for mold, and can cause fine scratches. It is essential to either store them in a case or regularly remove dust using an air duster or blower as part of maintenance.

Temperature and Humidity Management | Optimal Storage Environment for Nendoroids

• Recommended Temperature and Humidity Values
• Seasonal Temperature and Humidity Measures
• Recommended Goods for Managing Temperature and Humidity

Managing temperature and humidity for storing Nendoroids is the most fundamental and important factor in preventing deterioration. By maintaining an appropriate environment, you can prevent issues such as stickiness, deformation, and mold before they occur.

The ideal environment for storing figures is almost the same as that which is comfortable for humans. In other words, adjusting the room temperature with air conditioning and controlling humidity with dehumidifiers or humidifiers creates an ideal environment for Nendoroids as well. However, the methods of countermeasures may vary depending on the season and region, so adjustments according to your home environment are necessary.

Particular attention is needed during the high humidity of the rainy season, high temperatures in summer, and extreme dryness in winter. During these times, regularly check the temperature and humidity gauge and operate dehumidifiers or humidifiers as needed. Since the environment can vary greatly depending on the storage location, it is recommended to measure the temperature and humidity in the actual place where you store the Nendoroids, such as inside closets or shelves.

Recommended Temperature and Humidity Values

The optimal temperature for storing Nendoroids is 18–25℃, and the humidity is 40–60%. Keeping within this range minimizes the deterioration of PVC and ABS resins.

When the temperature exceeds 30℃, the plasticizers in the PVC can start to leach out, causing stickiness. Additionally, in high-temperature environments above 35℃, the risk of material deformation increases. Conversely, at low temperatures below 10℃, the material may harden and become more susceptible to impact.

When humidity exceeds 70%, the risk of mold growth increases sharply, and if it exceeds 80%, mold can proliferate within a few days. On the other hand, in extremely dry conditions with humidity below 30%, the flexibility of the material is lost, leading to paint cracking and material brittleness. Installing a temperature and humidity gauge and maintaining this recommended range is key to long-term storage.

Seasonal Temperature and Humidity Measures

Japan's climate changes significantly with the seasons, so appropriate measures need to be taken for each season. Spring and autumn are relatively stable, but summer, winter, and the rainy season require particular attention.

During the rainy season (June to July), humidity often exceeds 80%, making mold prevention the top priority. Use a dehumidifier or the dehumidification mode of your air conditioner. Additionally, placing desiccants or silica gel inside the storage case can effectively manage localized humidity.

In summer, both high temperatures and high humidity need to be monitored, while in winter, measures against dryness due to heating become important. Let's look at specific countermeasures for each season.

Measures Against High Temperature and Humidity in Summer

In summer, room temperatures often exceed 30℃, and humidity can be 70% or more, so simultaneous management of temperature and humidity with air conditioning is the most effective. Setting the temperature to around 24–26℃ and using the dehumidification mode can maintain a comfortable environment.

If you cannot keep the air conditioner running constantly, place a dehumidifier near the storage area. Also, use blackout curtains or UV-cut films on windows that receive direct sunlight to prevent room temperature from rising. Since closets and shelves can easily trap air, it is also important to regularly open the doors for ventilation. Change the desiccants every 1 to 2 months to ensure they can effectively absorb moisture.

Measures Against Dryness in Winter

In winter, indoor air becomes extremely dry due to heating. If humidity falls below 30%, the materials of Nendoroids may harden, leading to paint cracking and material brittleness. Using a humidifier to maintain humidity around 40–50% is ideal.

However, over-humidifying can cause condensation, which increases the risk of mold, so caution is necessary. Continuously monitor with a temperature and humidity gauge to maintain the appropriate range. It is also important not to place Nendoroids near heating appliances. Areas directly exposed to hot air from fan heaters or air conditioners can become locally high in temperature, causing deformation.

Recommended Goods for Managing Temperature and Humidity

To effectively manage temperature and humidity, utilizing appropriate goods is essential. The first essential item is a temperature and humidity gauge. A digital type that can record maximum and minimum temperature and humidity will allow you to understand daily fluctuations, making an investment of around 1,000 to 2,000 yen sufficient.

Dehumidifiers are effective for managing humidity in storage cases and closets. Silica gel types can be reused and are economical, but they require regular drying. Disposable types have clear replacement periods and are easy to maintain. For display cases, thin dehumidifying sheets are recommended.

Air conditioners and dehumidifiers are effective for managing the overall environment of a room, but if you're concerned about electricity costs, there are also methods to circulate air using small dehumidifiers or circulators specifically for storage. Additionally, using a smart temperature and humidity meter allows for remote monitoring via smartphone, enabling you to check the environment even while you're out. There is also a feature that sends alerts if humidity exceeds the set value, allowing for worry-free storage.

Direct Sunlight & UV Countermeasures | How to Prevent Fading and Discoloration

• Effects of UV Rays on Nendoroids
• How to Choose Storage Locations to Avoid Direct Sunlight
• How to Utilize UV Cut Films and Covers

UV rays are the greatest enemy of Nendoroid degradation. Direct sunlight, as well as UV rays emitted from indoor lighting and fluorescent lights, can cause fading and yellowing over the long term. Once a figure has discolored, it is very difficult to restore it, so prevention is of utmost importance.

In particular, white or light-colored Nendoroids are susceptible to UV rays, and visible yellowing can occur after just a few months of direct sunlight. Additionally, not only does the paint fade, but the material itself also deteriorates, which can lead to brittleness over the long term.

UV countermeasures can be approached in two ways: "blocking UV rays" and "storing in places that are not exposed to UV rays." Ideally, combining both methods can more reliably protect Nendoroids. Consider your costs and effort while choosing measures that suit your environment.

Effects of UV Rays on Nendoroids

Damage from UV rays can be mainly classified into three categories: "fading," "yellowing," and "material degradation." Fading occurs when the pigment molecules in the paint are broken down by UV rays, and particularly vibrant colors like red and blue can noticeably fade within a few months.

Yellowing is often seen in white or light-colored materials, caused by additives in PVC or ABS resin oxidizing due to UV rays. Once a material has yellowed, it is difficult to restore, and treating it with bleach or similar substances can actually damage the material.

Material degradation is less visible but is the most serious problem in the long term. UV rays can break the molecular bonds of the material, causing it to harden and become brittle. As a result, even light impacts that normally wouldn't cause breakage can increase the risk of parts breaking. These damages accumulate over time, so while there may not be issues in the short term, degradation will definitely become apparent over several years.

How to Choose Storage Locations to Avoid Direct Sunlight

The most basic and effective UV countermeasure is to choose a location that is not exposed to direct sunlight. If you are more than one meter away from a window, you can almost completely avoid the effects of direct sunlight. Especially for south-facing or west-facing windows, which have longer sunlight exposure, try to place items as far away as possible.

Inside closets or storage shelves is an ideal storage location as they are not exposed to direct sunlight. However, they tend to trap air and have higher humidity, so regular ventilation and the installation of dehumidifiers are necessary. Additionally, since you cannot view items in complete darkness, consider other measures if you want to display them.

When displaying, it is important to use indirect lighting and avoid direct exposure to fluorescent lights. LED lighting is ideal for figure lighting as it contains almost no UV rays. Also, since the angle of sunlight changes with the seasons and times of day, it is important to regularly review your storage location to ensure that it is not unintentionally exposed to direct sunlight.

How to Utilize UV Cut Films and Covers

If you want to implement UV countermeasures while displaying, acrylic or glass cases with UV cut features are optimal. Products with 90% or more UV cut rate can almost completely block indoor UV rays. In particular, cases with UV400 cut specifications can cut both UVA and UVB rays, providing even higher protection.

UV cut films for windows are also effective. Choose a type with high transparency that does not darken the room when applied, so it won't interfere with daily life. They can be purchased at home centers or online for about 2,000 to 5,000 yen, and you can apply them yourself. If you are renting, choose a type that can be applied and removed easily.

While UV-cut sprays and coatings are commercially available, please avoid using them directly on the Nendoroid body. Depending on the compatibility with the material, they may cause discoloration or deterioration. It is safest to use them only on cases or windows, ensuring that they do not come into contact with the Nendoroid body. Additionally, using blackout curtains or UV-cut curtains can further enhance the effectiveness.

Choosing Storage Cases and Display Cases

• For Display Enthusiasts | Attractive Storage Cases
• For Long-Term Storage | Storage-Focused Cases
• Recommended Cases by Budget

The optimal case for storing Nendoroids differs depending on whether you want to "enjoy displaying them" or "focus on long-term storage." If display is a priority, high-transparency acrylic or glass cases are suitable, while for long-term storage, storage boxes with excellent light-blocking and airtight properties are appropriate.

Key points to consider when choosing a case include UV-cut functionality, dust prevention performance, size, ventilation, and budget. In particular, UV-cut functionality is directly related to preventing long-term deterioration, so it should be considered an essential feature when displaying. On the other hand, when storing in dark places like closets, prioritizing moisture control over UV-cut functionality is advisable.

Additionally, Nendoroids typically require about 10 cm in height, and about 12 to 15 cm including the base. When displaying multiple figures or larger Nendoroids, it is wise to consider expandability when selecting a case. Budgets can range widely from under 1,000 yen to over 10,000 yen, allowing for selection based on purpose.

For Display Enthusiasts | Attractive Storage Cases

For those who want to protect their Nendoroids while displaying them, a display case with high transparency and UV-cut functionality is recommended. Acrylic cases and glass cases are the main options, each with their own advantages and disadvantages.

When choosing a display case, the method of opening and closing the case is also important. Front-door types make it easy to take figures in and out, allowing for easy pose changes and cleaning, but they may have slightly lower airtightness. Completely sealed types have high dust prevention performance but can be cumbersome to open and close. Additionally, cases with back mirrors are recommended as they allow you to enjoy the back view of the Nendoroids.

If you want to focus on lighting, choose cases with LED lighting or designs that allow for retrofitting lighting. Warm-colored LEDs create a cozy atmosphere, while white LEDs enhance visibility of details. However, even with LEDs, prolonged exposure can generate heat, so ventilation should also be considered.

Advantages and Disadvantages of Acrylic Cases

Acrylic cases are lightweight, highly transparent, and relatively affordable, making them the most popular type of display case. If you choose an acrylic case with UV-cut functionality, you can beautifully display your Nendoroids while effectively protecting them from UV rays.

Advantages: Lightweight and easy to move or rearrange, high safety as they are less likely to break if dropped, more affordable than glass making it easier to purchase multiple, easy to process and customize later, high transparency for easy visibility.

Disadvantages: Prone to static electricity attracting dust, requiring frequent cleaning, can scratch easily and may become cloudy with long-term use, lacks the premium feel compared to glass, and cheaper products may lack UV-cut functionality. Price ranges from about 1,000 to 5,000 yen, with sizes mainly for 1 to 3 Nendoroids. Regularly wiping with a soft cloth can help maintain transparency.

Advantages and Disadvantages of Glass Cases

Glass cases offer a premium feel and excel in maintaining long-term transparency, making them a serious choice for display cases. They are suitable for those who want to showcase their collection beautifully or store expensive Nendoroids.

Advantages: Resistant to scratches and can maintain transparency for a long time, less prone to static electricity and dust accumulation, has a premium feel and enhances room decor, UV-cut glass provides high UV protection, and their weight gives them high stability.

Disadvantages: Heavy and difficult to move, risk of breaking from falls or impacts, more expensive than acrylic (ranging from about 5,000 to 20,000 yen), limited options for size and shape, and earthquake measures are essential. When choosing a glass case, always use an anti-tip mat or anti-tip hardware to ensure safety. Additionally, selecting products made of tempered glass can reduce the risk of breakage in case of an accident.

For Long-Term Storage | Storage-Focused Cases

When storing for a long time or if you have a large collection that cannot all be displayed, cases that prioritize storage are suitable. Choose products that emphasize light-blocking, moisture-proofing, and stacking performance for efficient storage.

Cases for long-term storage prioritize protection over transparency. Opaque storage boxes can completely block direct sunlight and prevent deterioration from ultraviolet rays. Additionally, highly airtight boxes prevent dust intrusion, and by adding a dehumidifier, moisture control can be thoroughly managed.

However, complete sealing can cause air to become stagnant, leading to mold, so moderate breathability is also necessary. Open the boxes about once a month to exchange the air and check the condition of the dehumidifier. Also, when stacking multiple boxes, be careful not to put too much weight on the bottom box.

Comparison of Box Storage and Case Storage

There is an opinion that storing Nendoroids in their original boxes is the safest, but in reality, both box storage and case storage have their own advantages and disadvantages.

Advantages of Box Storage: Can be stored in the condition at the time of purchase, providing peace of mind; prevents loss of parts; the box itself serves as light-blocking and cushioning material; easier to maintain collection value. Disadvantages: Takes up space; inconvenient to check contents as they are not visible; the box itself may deteriorate; prone to moisture accumulation.

Advantages of Case Storage: Efficiently stores in a space-saving manner; contents are easy to see and manage; easier to manage ventilation and humidity; can store multiple figures together. Disadvantages: Lack of a box may decrease collection value; requires ingenuity in parts management; incurs additional costs. The choice between the two should be made considering storage duration, space, and future resale plans. It is also possible to store the box separately and move the Nendoroid itself to a case.

Recommended Storage Boxes and How to Choose

For long-term storage boxes, prioritize airtightness, durability, and stacking performance. Recommended are plastic storage boxes with lids that fit the size of Nendoroids.

Specifically, a box with internal dimensions of about 30cm wide x 20cm deep x 15cm high can store 3 to 5 Nendoroids. Transparent lid boxes are convenient for checking contents, but if light-blocking is a priority, choose opaque types. Additionally, boxes with gaskets have high airtightness and can prevent moisture and dust intrusion.

Recommended products include Muji's polypropylene cases, IKEA's SAMLA storage boxes, and Tenma Fits cases sold at home improvement stores. Prices range from 500 to 2,000 yen, making it less burdensome even when purchasing multiple boxes. Place a dehumidifier inside the box and use air caps (bubble wrap) to separate the Nendoroids to ensure safety.

Recommended Cases by Budget

By choosing the optimal case according to your budget, you can achieve effective storage while keeping costs down. Here, we introduce recommended cases in three budget ranges: under 1,000 yen, around 3,000 yen, and over 5,000 yen.

Under 1,000 yen: Acrylic cases from 100 yen shops (Daiso, Seria), transparent plastic storage boxes. They do not have UV-cut functions, but are sufficient for dust prevention and organization. Suitable for storage in places not exposed to direct sunlight.

Around 3,000 yen: Acrylic cases with UV-cut functions (for 1-2 Nendoroids), display boxes with LED lighting. From this price range, UV-cut functions are often standard, allowing for both display and protection. Available for purchase at online shops and hobby shops.

Over 5,000 yen: High-quality UV-cut acrylic cases (for 3-6 Nendoroids), glass display cases, dedicated figure cases. Features such as UV400 cut, back mirrors, LED lighting, and rotating bases are abundant, making them ideal for serious collection displays. As a long-term investment, they can perfectly protect your valuable Nendoroids. Gradually upgrading cases according to budget and purpose is also a good approach.

Specific Steps and Checklist for Long-Term Storage

• Preparation Work Before Long-Term Storage
• Correct Procedures for Packing and Storage
• Regular Maintenance and Check Items

When storing Nendoroids for a long time, proper preparation and regular maintenance are essential. By following the correct procedures during moves, seasonal changes, or collection swaps, you can minimize deterioration.

The basics of long-term storage are to "keep it clean and sealed, and check it regularly." If you store items with dust or dirt on them, deterioration may progress from there. Additionally, if left unattended, mold or stickiness may develop without you noticing.

Here, we will specifically explain the preparatory work before long-term storage, the correct procedures for packing and storing, and regular maintenance methods. We have organized it in a checklist format for your reference during storage.

Preparatory Work Before Long-Term Storage

Before long-term storage, be sure to clean your Nendoroid. If you store it with dust or fingerprints, deterioration will begin from there. Use a soft brush or air duster to remove dust, and gently wipe with a neutral detergent diluted with water if necessary. If you use detergent, be sure to completely remove it with a damp cloth and dry it with a clean cloth.

Next, check the parts. Ensure that all replacement face parts, hand parts, and accessories are present, and check for any missing base or joint parts. It is important to check before storage, as it may be difficult to obtain missing items later. Store parts in small ziplock bags to prevent loss.

It is also recommended to take photos of the pre-storage condition. By photographing the overall view and details with a smartphone, you can compare changes in condition later, which can help identify the cause in case of deterioration. Recording the date and time of the photos will make it easier to keep track of the storage period.

Correct Procedures for Packing and Storing

Once cleaning and part checking are complete, pack and store them properly. Wrap the Nendoroid body in air caps (bubble wrap) to protect it from shocks. Be especially careful with protruding parts and small pieces, as they are prone to breakage.

Inside the storage box, create dividers to prevent Nendoroids from touching each other. Using cardboard, sponge, or small storage cases to separate them can reduce the risk of parts breaking due to shocks during transport. Additionally, placing cushioning material at the bottom of the box increases safety.

Always include a dehumidifier or silica gel inside the box. To avoid direct contact with the Nendoroid body, place it in a cloth bag or position it in a corner of the box. Since dehumidifiers need to be replaced every 2-3 months, it is helpful to note the replacement date inside the box for easier management. Finally, securely close the box lid and store it in a place that is not exposed to direct sunlight and has minimal temperature fluctuations.

Regular Maintenance and Check Items

Even during long-term storage, open the box and check the condition about once a month. The check items are as follows:

Monthly Check: Check the condition of the dehumidifier and replace it if necessary, check for moisture or mold inside the box, observe any changes in the appearance of the Nendoroid (discoloration, stickiness, deformation), and ensure no dust has entered. If the dehumidifier is saturated, it is a sign that humidity management is insufficient, so a review of the storage location is necessary.

Semi-Annual Check: Take out the Nendoroid for detailed observation, check the movement of parts, check for deterioration of the base and joints, compare changes with the pre-storage photos and record them, and check the condition of the air caps and dividers for replacement. At this time, lightly clean it and rewrap it in new air caps for added safety.

Annual Check: Review the temperature and humidity environment of the storage location, check for deterioration of the storage box itself, consider improvements to the storage method, and reorganize the entire collection and reassess priorities. Keeping a record of regular maintenance allows for early detection of signs of deterioration, helping to keep your precious Nendoroids beautiful for a long time.

NG Storage Methods to Avoid and Their Reasons

• Worst 5 NG Storage Methods
• Common Storage Failures and Solutions

Understanding what not to do in terms of storage is just as important as knowing the correct storage methods. There are many cases where well-intentioned storage methods can actually cause serious damage to Nendoroids.

Many NG storage methods stem from neglecting to manage temperature, humidity, or ultraviolet light. Additionally, misconceptions such as "if it's completely sealed, it's safe" or "if it's in a box, it's fine" can lead to trouble. Here, we will explain the particularly NG storage methods to avoid and the scientific reasons behind each.

Even if you are already using NG storage methods, early improvement may stop the progression of deterioration. Use this chapter as a reference to review your storage methods.

Worst 5 NG Storage Methods

Here are the top 5 worst storage methods that many collectors tend to fall into, presented in order of severity. These methods should be absolutely avoided as they rapidly accelerate deterioration.

These NG storage methods are problematic on their own, but when multiple methods overlap, they can cause even more serious damage. For example, if you are stacking items naked by the window, you will be subjected to triple damage from ultraviolet rays, temperature changes, and weight.

Placing in a location with direct sunlight by the window

Storing by the window is the most prohibited NG action. The ultraviolet rays contained in direct sunlight can cause fading and yellowing of Nendoroids in just a few weeks. Especially for materials that are white or light-colored, visible yellowing can occur within 1 to 2 months. Additionally, during summer, the surface temperature by the window can exceed 40°C, causing PVC plasticizers to seep out and lead to stickiness. Furthermore, in winter, the cold air from the window can lower the temperature, increasing the risk of mold due to condensation. Even through lace curtains, ultraviolet rays can penetrate, so avoid storing by the window.

Placing near air conditioning or heating appliances

Being near the air conditioning vents or heating appliances is very dangerous as it can become locally high in temperature. In places where warm air directly hits, even if the room temperature is appropriate, it can exceed 30°C locally, which may cause deformation of the Nendoroid. Especially near fan heaters or halogen heaters, there have been reports of deformation or melting occurring within a few hours. Additionally, the air from air conditioning is dry, so prolonged exposure can harden the material, leading to paint cracking and material brittleness. Keep at least 1 meter away from heating appliances.

Completely sealed environment with no air circulation

The idea that "sealing means safety" is half correct and half wrong. Sealing is effective for protection against dust and ultraviolet rays, but a completely sealed environment with no air circulation becomes a breeding ground for mold. Especially during the humid rainy season or summer, the humidity inside sealed containers can exceed 80%, and mold can proliferate within a few days. Additionally, plasticizers volatilized from PVC can become trapped inside sealed containers, worsening stickiness. When using highly sealed containers, it is important to include a dehumidifier and open them once a month to exchange the air.

Common Storage Failure Examples and Solutions

Here are examples of common storage failures and their solutions. If addressed early, it may be possible to minimize damage, so respond immediately upon noticing symptoms.

Stickiness (Plasticizer Seepage): Occurs due to high-temperature environments or aging. In mild cases, gently wiping with a cloth soaked in anhydrous ethanol may improve the situation. However, be careful not to rub too hard as it may peel off the paint. After wiping, store in a cool place and check regularly. Severe stickiness cannot be completely removed, so prevention is the most important.

Discoloration/Yellowing: Occurs due to ultraviolet rays or aging, and it is very difficult to restore. Avoid using bleach or melamine sponges as they can damage the material. To prevent further progression, immediately move to a place not exposed to direct sunlight and store in a UV-cut case. Prevention is the only countermeasure.

Lost Parts: Small replacement parts are easy to lose, so manage them in small ziplock bags or parts cases from the time of purchase. If lost, you may be able to obtain them from official support or second-hand parts sales sites, but there are many cases where they are difficult to obtain. Always check the number of parts before storage and record them in photos to enable early detection of loss.

Summary | How to Keep Nendoroids Beautiful for a Long Time

The basic storage methods to keep Nendoroids beautiful for a long time are maintaining an environment with a temperature of 18-25℃ and humidity of 40-60%, UV protection by avoiding direct sunlight, and storing them in cases to protect from dust. By following these, it is possible to keep them in beautiful condition for over 10 years.

Storage methods are not a one-time setup; they need to be reviewed according to seasonal changes and environmental shifts. Make it a habit to regularly check temperature and humidity and perform maintenance to protect your valuable collection from deterioration.

It may be difficult to create a perfect storage environment from the start, but it is sufficient to improve gradually from what you can do. Start by avoiding direct sunlight, installing a thermometer and hygrometer, and placing them in cases. With the right storage methods, enjoy your Nendoroid collection for a long time.
