Good Smile Company’s own support site says the quiet part out loud: “deterioration is inevitable,” and the maker does not recommend keeping figures sealed in the box. What you control is how fast it happens, and the enemies are the ordinary ones in an American home: a south-facing window, a heating vent, a humid basement, a cat. This guide takes the maker’s written guidance, adds what collectors in Tokyo actually do, and prices the display options from a bare shelf to a $280 IKEA cabinet, so a figure you paid duty on stays the color it arrived in.

Everything attributed to the maker below comes from Good Smile Company’s English support pages (which also cover figma and Max Factory, since their support routes to the same help center). Where the advice is collector practice rather than maker guidance, we say so.

What actually damages a PVC figure

Good Smile’s checklist for newly arrived figures names three risks of leaving them boxed: figures “may deteriorate rapidly in hot and humid environment,” the plasticizers in the PVC can vaporize and leave the surface sticky and prone to further deterioration, and you will not notice a defect or missing part until the replacement window has closed. The same page’s storage section adds four rules: display or store in a well-ventilated place away from direct sunlight, take figures out regularly if they live in a box or container, avoid strong fluorescent light because colors may fade, and do not leave Nendoroid parts pressed against each other for long stretches, because color can transfer.

Two more maker pages fill in the edges. The cloth-outfit page warns that dark fabric can stain PVC through friction, heat and humidity, recommends a piece of vinyl between the figure and the cloth, and states flatly that Good Smile will not support color-transfer claims. The partner FAQ notes that figure materials stiffen in cold weather, which is why parts fight you in a January unboxing.

Notice what is not on those pages: no temperature ceiling, no humidity percentage, no cleaning recipe. The maker’s position is a direction of travel (cool, dry, dark-ish, ventilated) rather than a number, and we have kept it that way below.

Display options compared

A few notes on the table. IKEA describes its tempered glass as four to five times stronger than regular glass, which matters for a cabinet a toddler leans on, but the MILSBO page says nothing about blocking ultraviolet light and we found no UV claim for the BAGGEBO either. Do not assume a glass door protects the paint. The UV numbers on acrylic cases are the sellers’ claims and vary by product and even by production batch: one UK specialist seller targets 99% but listed one production batch at 91 to 92%. Treat “UV-cut acrylic” as better than nothing, not as a license to put the cabinet in the sun.

Prices are what we saw on September 4, 2026 (the Amazon figures are rough US-dollar equivalents at that day’s exchange rate, so confirm on the listing) and they change often; the IKEA numbers move with promotions; the MILSBO was on a 20%-off tag when we looked. The 8 × 8 × 12 inch box is the size most Amazon sellers pitch as “one 1/7-scale figure,” and the smaller seller’s own advice is to buy 3 to 5 cm larger than the figure in every direction, which is good advice for any case.

Recommendation by situation

A south-facing room or a window seat. Take the window off the table: the maker’s first rule is “avoid direct sunlight,” and no case fixes a figure that sits in a sunbeam every afternoon. Put the cabinet on the wall that faces away from the window and treat a UV-claim acrylic case as a second layer, not the first.

Forced-air heating or a radiator. The Good Smile checklist ties fast deterioration to heat and humidity together, and a vent or radiator is the one spot in a room that delivers heat directly to whatever sits above it. Keep figures away from vents and radiators, and out of the direct blast of a space heater.

Humid climates: Gulf Coast, Florida, a basement anywhere. The maker’s answer is ventilation, not sealing: a well-ventilated spot, and boxed figures taken out regularly. Some collectors add silica gel packets to storage boxes; that is collector practice, not maker guidance, so change the packets rather than trusting them forever.

Cats, dogs and kids. This is where the IKEA cabinets earn their money over open shelves. A glass-door cabinet with a strip of museum putty under each base solves the earthquake and the cat with one purchase, which is why this combination is so common in Tokyo apartments. Anchor any cabinet that tall to the wall.

One or two showcase figures in an ordinary room. A single acrylic case per figure is cheaper than a cabinet, keeps dust off, and the magnetic door means you can still turn the figure. The three items below are US Amazon listings that ship domestically, so the import duty math that applies to the figure itself does not apply to the case.

📦These three are US Amazon marketplace listings that ship domestically, so no import duty applies. Prices are what we saw on September 4, 2026 and change often; UV percentages are the sellers' claims, not something we have measured.

Step by step: from box to shelf

1. Open it the week it arrives. The maker’s checklist asks you to unpack as soon as possible and inspect for defects, because a missing or damaged part found a year later is past any replacement window. If you ordered through a Japanese shop, our pre-order basics covers who to contact when something is wrong.

2. Keep the blister. The clear plastic tray is molded to the figure and is the safest thing to store it in if you ever move or sell. Fold the box flat or keep it whole; either way, store both away from sunlight and damp, the same way you would store the figure. The secondhand market grades boxed and unboxed figures differently, and if you have walked the Nakano Broadway shops you have seen the boxed ones priced on the shelf and the loose ones in a bin.

3. Place it. Away from the window, away from vents, not under a strong fluorescent tube. Give heavy poses (one leg, a long weapon, a cape) a spot where nothing will brush them. If a figure has a cloth outfit, slip a piece of vinyl between the fabric and any PVC it touches, as the maker suggests.

4. Fix the base with museum putty. Roll a small piece until it softens, press it to the underside of the base, and set the figure down. To remove, lift and twist; the putty is reusable and leaves nothing behind. In Tokyo this is earthquake insurance; in the US it is cat insurance.

5. Clean with mild soap and water. For dust, a soft brush or a blower. For the sticky film that shows up on older figures, collectors on MyFigureCollection wash with a drop of dish soap and water, rinse and air-dry. Keep water away from any electronics or cloth parts. This is collector practice; Good Smile explains the cause (plasticizer vaporization) but does not publish a cleaning method.

6. Stuck parts: the maker’s warm-water method. Good Smile’s own guidance for parts that will not come off is a hair dryer, or immersing the parts in warm water of about 40°C (104°F) for 15 minutes, with a warning not to burn yourself. The same page notes that PVC will not melt or break unless it reaches a very high temperature, so a brief warm soak is safe by the maker’s account.

7. What not to do. No rubbing alcohol: one collector in that same MFC thread found it stripped a matte finish and cracked a stand. Skip acetone and other solvents for the same reason, and test anything stronger than soap on the underside of the base first. Never leave figures in a car: a 2018 study reported by Live Science found a cabin parked in the sun on a 95°F day averaged 116°F (47°C) within an hour, with dashboards averaging 157°F (69°C), and even shaded dashboards reached 118°F (48°C). Attics and garages swing with the weather and are not climate-controlled rooms; store overflow in a closet inside the living space.

FAQ

Should I keep the box? Keep the blister at minimum. Boxed figures usually command more on the secondhand market and travel safer, and a flat-folded box takes little space. Just store the box the way you store the figure: dry, dark, ventilated. If you decide to sell later, the box also helps a buyer check authenticity; our bootleg-spotting guide explains what they look for.

My figure feels sticky. Is it ruined? Usually not. Good Smile attributes stickiness to plasticizer vaporizing out of the PVC, which its checklist links to boxed storage in heat and humidity. Collectors wash it off with dish soap and water. If it keeps coming back, the display spot is too warm or too closed-in.

How bad is sunlight, really? Bad enough that “avoid direct sunlight” is the maker’s headline storage rule. Fading is gradual and uneven, so you notice it on the side that faced the window. Move the figure rather than trusting a case’s UV claim.

What about fluorescent lights and LED strips? Good Smile’s checklist says not to display under strong fluorescent light because colors may fade. The maker does not address LED strips on that page; the IKEA cabinets are sold “prepared for lighting,” so if you add a strip, keep it dim and away from the figures, and watch for any heat it gives off inside a closed cabinet.

How long can a figure stay in the box? Good Smile’s answer is that it should not: the maker does not recommend keeping figures unopened, and asks that any figure stored in a box be taken out regularly. If you have a backlog, at least open each one, inspect it, and air it out now and then.

Can I fix a leaning figure? Collectors do it by warming the bent part gently with warm water and supporting it while it cools, and there is a long thread on MyFigureCollection about the technique. Good Smile does not publish a leaning fix; what it does publish is the 40°C, 15-minute warm-water method for stiff parts, and the reassurance that PVC needs much higher heat to melt. Work slowly, support the figure while it cools, and accept that a figure that has leaned for years may not fully straighten.
