Understanding the Materials That Make Up Your Collection

Most My Hero Academia collectibles — from prize figures and scale statues to Nendoroids and Figma — are crafted from a blend of synthetic materials. Knowing what you are dealing with is the first step to proper preservation. The most common plastics are PVC (polyvinyl chloride) and ABS (acrylonitrile butadiene styrene). PVC is flexible and often used for detailed body parts, while ABS provides rigidity for stands, weapons, and joint connections. Many premium figures also incorporate polyresin, vinyl, and polyester-based paints. Each of these materials reacts differently to light, humidity, and handling.

PVC, for example, contains plasticizers that can migrate over time, causing stickiness or a tacky surface — a condition collectors dread. This is often triggered by heat and prolonged enclosure without ventilation. ABS can become brittle with exposure to UV light. Paints, especially those on prize figures, may not be sealed as thoroughly, making them susceptible to scratching and fading. Recognizing these vulnerabilities helps you build a care routine that targets the actual threats your figures face. Good Smile Company's official care guide offers a concise overview of how to handle PVC and ABS figures from one of the world's leading manufacturers, and their maintenance advice applies directly to many My Hero Academia lines like Nendoroid and Figma.

Handling Your Collectibles Correctly

Fingerprints, skin oils, and accidental drops are the silent destroyers of any collection. Whether you are unboxing a new addition or rearranging a display, always start with clean hands. Even if you have just washed them, natural oils reappear quickly, so consider wearing gloves for high-value or delicate pieces. Use lint-free cotton or nitrile gloves. Nitrile gloves provide excellent grip and won't leave fibers behind, making them ideal for painted surfaces. Avoid powdered gloves; the fine powder can lodge in crevices and attract moisture.

When lifting a figure, never grab it by the extremities — a protuding headpiece, a cape, or an extended arm. Those are often the most fragile stress points. Instead, support the item from the base and gently cradle the torso. For articulated figures like Revoltech or Figma, move joints slowly and deliberately, never forcing them beyond their natural range. If a joint feels stiff, do not twist it. Warm the area slightly with a hair dryer on the lowest setting for a few seconds to relax the plastic. Dry heating is a safe method because it gently softens PVC without introducing moisture. As soon as the joint moves, stop.

Particularly delicate parts include translucent effect pieces (such as battle aura flames, energy blasts, or character-specific quirk effects). These are often cast in a more brittle clear plastic that can snap under the slightest pressure. Always handle them last, after the main figure is securely in place.

Creating the Perfect Storage Environment

How you store your figures when they are not on display determines their longevity just as much as handling. The ideal environment controls four factors: light, temperature, humidity, and dust. Even a few minutes of neglect can cause irreversible damage over years.

Light and UV Exposure

ultraviolet radiation is the number one enemy of painted plastics. It breaks down polymer chains, causes yellowing (especially in white or light-colored PVC), and bleaches colorful paint. Never place a display in direct sunlight. Even indirect daylight that streams through an untreated window carries significant UV energy. If your room has windows, invest in UV-protective window film or blackout curtains. For display cabinets, use cases fitted with UV-filtering acrylic or glass. You can also retrofit existing glass shelves with adhesive UV-blocking sheets. LED lighting is generally safe for figures, as it emits negligible UV, but keep the lights a few inches away to avoid heat buildup. A good resource for understanding light damage and preservation is the American Institute for Conservation’s "Caring for Your Treasures" guide, which outlines universal rules for protecting collectible objects.

Temperature and Humidity Control

Aim for a stable room temperature between 60°F and 75°F (15°C – 24°C) and relative humidity between 40% and 50%. Fluctuations are far more harmful than slightly elevated steady numbers because they cause materials to expand and contract, leading to cracking paint and loosening joints. Avoid storing figures in attics, basements, or garages where temperatures can swing wildly and humidity can condense. If you live in a humid climate, a dehumidifier in the room is a worthwhile investment. For added protection inside enclosed display cases or storage boxes, include silica gel packets or reusable desiccant canisters. These absorb excess moisture without adding dust. Change or recharge them as indicated by the manufacturer — often a color change from blue to pink signals saturation.

Dust and Airborne Debris

Dust is abrasive. Over time, dust settled into paint crevices acts like sandpaper when you try to wipe it off, causing micro-scratches. The best defense is keeping the collection enclosed in sealed display cabinets with gasketed doors. If open shelving is your only option, use individual clear acrylic display boxes for the most treasured pieces. Regularly vacuum the room with a HEPA filter to reduce airborne particles. A simple air purifier running nearby can make a noticeable difference in dust accumulation rates.

Choosing Shelving and Cases

Opt for shelving materials that are stable and non-reactive. Painted metal, glass, and sealed wood are good choices. Avoid unpainted particle board or MDF, which can off-gas formaldehyde and other volatile organic compounds that accelerate plastic degradation. Lining shelves with a soft, acid-free mat or polyester felt also prevents paint transfer if a figure base is set directly on a hard surface. For long-term boxed storage, use acid-free, lignin-free archival boxes — sources like Gaylord Archival offer a wide variety of sizes that are perfect for boxing up rare figures while you cycle your display.

Routine Cleaning Without Damage

Figures gather dust no matter how sealed the display seems. A weekly or biweekly dusting routine keeps maintenance minimal and prevents embedded grime. The golden rule: always use the gentlest method first, and never wet-clean unless you are sure the surface can handle it.

Basic Dusting

Your primary tool is a large, soft camel-hair makeup brush or a high-quality artist’s brush. A brush with natural fibers is less likely to generate static than a synthetic one. Hold the figure by its base and gently whisk dust from the top down — hair first, then face, torso, limbs, base. For stubborn dust caught in textured areas (like costume folds or blast effects), use a small, clean microfiber cloth in a dabbing motion. Do not rub; rubbing can push particles into paint and create fine scratches. Canned compressed air is useful for blowing out crevices, but hold it upright and a few inches away, and never use it on loose or fragile parts that could be dislodged. Avoid air from an electric blower unless it has a HEPA filter, as unfiltered blowers can spray tiny oil droplets.

Wet Cleaning Stubborn Stains

Only move to moisture when dusting fails. Most painted PVC and ABS surfaces can tolerate a slightly dampened cloth. Use distilled water rather than tap water to avoid mineral deposits. Dampen a corner of a microfiber cloth, wring it out thoroughly until no water can drip, and lightly pat the soiled area. Immediately follow with a dry section of the cloth. Never spray water directly onto a figure; water can seep into joints, under decals, or into unsealed seam lines and kickstart internal rust or sticker adhesive failure.

For residues that refuse to budge, a tiny drop of mild, pH-neutral dish soap diluted in a bowl of water can be used. Dip a cotton swab, squeeze out excess, and gently roll it over the spot. Rinse the area with a new swab moistened only with clean water, then blot dry. Harsh cleaners, alcohol, acetone, or magic erasers are absolutely off-limits: they will strip paint, cloud clear plastic, or leave micro-abrasions.

Cleaning Fabric and Soft Goods

Some My Hero Academia figures — such as 1/6 scale dolls or custom cloth costume pieces — include real fabric. These require separate care. Surface dust can be lifted with a lint roller or narrow vacuum attachment covered in a nylon stocking. For deeper cleaning, test an inconspicuous area first. Hand-washing with cool water and a gentle soap like Woolite is usually safe, but avoid wringing. Reshape and air-dry on a flat surface away from heat. If the garment is glued to the figure, keep all moisture away from the glue line.

Long-Term Preservation Strategies

If you plan to store figures for months or years, the preparation determines whether they emerge pristine or sticky and ruined. PVC figures are notorious for developing a sticky surface when sealed airtight without ventilation, a phenomenon called plasticizer migration. The solution is to never store PVC items in completely sealed plastic bags for long periods — they need to breathe. Instead, wrap figures in unbleached, acid-free tissue paper and place them in archival cardboard boxes with a loose lid. This permits air exchange while blocking dust and light.

Keep the original packaging! The clear plastic blisters and boxes are engineered for the specific figure, but they are not necessarily archival. For long-term storage, it is safer to remove the figure from the blister and repack it in the tissue-lined box form described above, keeping the box for collectible value. If you must keep the figure in the blister, crack the plastic slightly to allow air to circulate. Many serious collectors have opened sealed decade-old figures to find them coated in sticky residue that required hours of cleaning.

For flat items like art prints, key frames, or signed shikishi boards, use polyester sleeves and acid-free backing boards. Frame them with UV-filtering glass and a mat that keeps the artwork from touching the glass. The same principles apply to T-shirts or cosplay props: store fabric items in breathable cotton garment bags, not plastic dry-cleaning bags.

Documentation is a preservation act in itself. Maintain a digital catalog with purchase dates, prices, condition notes, and close-up photos. Include detailed shots of manufacturer stamps, edition numbers, and any imperfections. This record supports insurance claims and helps you spot deterioration patterns over time.

Insurance and Protecting Your Financial Investment

A My Hero Academia collection can represent thousands of dollars in value, particularly as aftermarket prices for limited releases climb. Standard homeowners or renters insurance often covers collectibles only up to a low blanket limit, such as $500 to $1,000, and typically excludes damage from environmental factors like humidity. To adequately protect your collection, obtain a specialized collectibles insurance policy or a rider. Providers like American Collectors Insurance or Collectibles Insurance Services offer coverage that accounts for market value, not just original retail cost.

Before obtaining a policy, prepare a thorough inventory: high-resolution photos of each item, front and back, with any original boxes, and PDF documentation of confirmed sold listings on reputable auction platforms. Update the inventory annually. Store a digital copy off-site or in the cloud so that a loss at home does not destroy your records. Also, keep all original packaging and receipts — they significantly improve resale value and verify authenticity for an adjuster.

Common Mistakes That Damage Collections

  • Displaying in direct sunlight or under halogen bulbs — UV and heat wreck paint and warp plastic.
  • Cleaning with household sprays, glass cleaners, or baby wipes — these contain alcohol, ammonia, or moisturizers that degrade surfaces.
  • Stacking figures without protection — weight and friction cause paint rub and breakage. Use tiered risers to display them safely.
  • Ignoring sticky PVC — that tacky residue spreads and attracts dust. Clean it quickly with a gentle soap-and-water solution and let the figure air out.
  • Applying adhesives or sticky tack directly to paint — to secure a foot to a shelf, use museum putty only on the bottom of the base, never on the figure itself.
  • Storing in extreme temperatures — attic heat can soften and warp figures, while freezing garages can make plastic brittle.

When Restoration Becomes Necessary

Despite your best efforts, accidents happen. A clean break at a limb or accessory can often be repaired with a tiny amount of cyanoacrylate glue (super glue) applied with a toothpick. For clear parts, use a glue formulated for transparent plastics, which dries without clouding. For paint chips, a careful color-match from model paints can hide the damage, but practice on a palette first. For widespread sticky PVC syndrome, a bath of lukewarm water and mild soap, followed by a thorough air-drying, often removes the residue. If the problem persists, the plasticizer has leached deep into the surface and professional restoration may be needed. The Anime Figures subreddit and specialized collector forums are excellent places to find step-by-step restoration guides from experienced collectors who have dealt with exactly these issues.

Displaying With Pride and Safety

A well-displayed collection is a joy, and safety does not mean hiding your figures in a dark vault. Use layered display strategies: place taller figures on back risers, group characters by theme or season, and add museum-style acrylic display boxes for ultra-rare pieces. Rotate the collection every few months to give stored items a chance to breathe and to reduce cumulative light exposure on your favorites. Document each new arrangement photographically; over time, these pictures become a visual diary of your collecting journey.

With careful handling, smart storage, and respectful cleaning, your My Hero Academia collection can remain as vibrant as the day you unboxed it. You preserve not just the financial value, but the emotional connection to the characters and stories that inspired you to start collecting in the first place.
