What I Learned After Filling Three Display Cases: The Laws of Light and Space That Display Cases Don't Tell You

The day I ordered my third display case, the door wouldn't close

Let me get straight to the point. The battle with space begins not when you purchase a figure, but when you take it out and stand it up. The day my third display case arrived, I spread out the assembly instructions and realized: there was no place to put this case. Only after pushing all the furniture in my room against the walls, moving my bed 30cm, and clearing two shelves of my bookcase could the door finally open 90 degrees. When I bought my first display case in 2017, I didn't know this. A case width of 43cm plus 15cm for door clearance plus 10cm behind for cable access means the actual footprint is 1.5 times the catalog specifications.

Placing a display case comes before filling it. You must position it 10cm from the wall to route the rear LED cables, and at least 1m from windows to avoid summer afternoon direct sunlight. A figure on the left end of my first display case, which I set up ignoring these distances, had lost a tone of hair color three years later. Even indirect light betrays you.

How many can you fit in one shelf without it feeling cramped

For 1/7 scale figures, three per shelf (approximately 40cm wide) is the limit. With four, it looks fine from the front, but from the side the faces of the back row get blocked by the shoulders of the front row. Cram in five and the bases start overlapping visually, and even with the lights on, the back row remains in shadow. In summer 2019, when several pre-orders arrived at once, I once stood six 1/8 scale figures on a single shelf. It looked plausible in photos, but every time I opened the glass door to rearrange, I had to remove the front row to touch the back row. By the end of that month, I had returned two back-row figures to their boxes.

Nendoroids follow different math. Up to eight per shelf feels spacious; from twelve onward it gets tight. The problem is that Nendoroids come with many interchangeable parts. To display all three face parts, six hand parts, and four accessory parts, four per shelf is appropriate. In the community, people say "you haven't truly displayed a Nendoroid until you display the parts too," but few actually do this. Because you'd need to buy yet another small acrylic case just for the parts.

With figmas, the space they occupy changes every time you change their pose. Arms-raised poses consume vertical space; legs-spread poses consume horizontal space. I once stood twelve figmas on one shelf, but three with dynamic poses meant the other nine were locked into standing-straight positions. I eventually reached the conclusion that action figures only have meaning when given room to move.

Why dust accumulates at different rates on upper and lower shelves

The topmost shelf of a display case accumulates less dust. This is because airflow when opening the door moves downward. Conversely, the bottom shelf is close to the floor and takes in fine dust every time you run the vacuum. Since 2018, I've placed ALTER figures with delicate paint finishes on the top shelf, and prize figures on the bottom. When I open the door to clean once a month, the top shelf needs only a light wipe with a dry microfiber cloth, while the bottom requires two passes with wet wipes to get clean.

The middle shelf is at eye level. In a room viewed while seated, 60cm from the floor is the golden zone; in a room viewed while standing, 140cm. This is where you place your oshi. This height is also most convenient for photography. No need to lift your smartphone—just hold it straight out and you get a level angle.

Since attaching LED strips to the back of my display cases, dust has become more visible. When light enters at an angle, even dust in 1mm gaps between hair parts shows up as shadows. Cleaning frequency has doubled since installing LEDs. But I think it's better to see the dust and wipe it than to leave dusty figures unknowingly.

LED strip color temperature changes a figure's impression

Warm white (3000K) and cool white (6500K) make the same figure look like different works. Under warm white, warm-toned hair (blonde, brown, pink) comes alive, but cool tones (silver, blue, purple) become murky. Cool white is the opposite. When I replaced my LED strips in 2020, I tested both. A 1/7 scale Hatsune Miku's hair-tip clear parts glowed emerald under cool white, but under warm white the green looked dull.

I ultimately chose neutral white (4500K) as a middle ground. It's acceptable for all colors, but perfect for none. If your collection concentrates on specific colors, it's better to choose accordingly. Many community posts recommend "smart LEDs with adjustable color temperature," but in actual use, few people adjust them with the remote every time. You end up using whatever color temperature you initially set for the entire year.

Brightness matters too. If the LED is too bright, highlights blow out on figure faces and flatten expressions. Too dim and you see only reflections on the glass surface rather than inside the case. I adjust mine to roughly match mid-brightness on a smartphone screen when viewed from 50cm away. The precise measurement, using a light meter app, falls between 300–500 lux.

The difference between acrylic cases and glass cases after five years

Acrylic is light, cheap, and easy to assemble. But after three years, micro-scratches accumulate on the surface. A single dust particle on your microfiber cleaning cloth leaves a 1mm scratch. A hundred of these make it look cloudy. I disposed of an acrylic case I bought in 2016 in 2021. The figures inside were fine, but the case looked worn and made everything look secondhand.

Glass is heavy, expensive, and breaks. But its transparency lasts ten years. The oldest glass case in my room was purchased in 2014, and it's still as clear as new. The tradeoff is hell when moving. Each glass panel weighs 2kg; a five-shelf case totals 12kg. During my 2019 move, disassembling and packing three glass cases took two hours, and reassembling took another two hours.

Acrylic cases suit small figures (Nendoroids, figmas, prize figures), glass cases suit scale figures. Acrylic for desktop use, glass for floor placement. I've occasionally seen community reports of desks warping when someone ignored this distinction and placed a glass case on a desktop.

Why figure colors fade even when avoiding direct sunlight

A figure on the left end of my display case, 2m from the window, had faded after five years. It wasn't in a spot where direct sunlight hit. Turns out at 4 PM, light reflected off the opposite wall was entering along the side of the case. Indirect light also contains UV rays. Thirty minutes daily for five years equals 900 hours.

Since applying UV-blocking film to my cases, the problem has diminished. Transparency drops about 5%, but I can place cases near windows without worrying about color fading. Film costs around 10,000 won for five A4-sized sheets. I applied it to the inside of the glass door. On the outside, the film edges peel easily.

In a summer room without air conditioning, PVC figures collapse. Literally—heads and arms droop downward. In summer 2018, after a business trip during a week when daily highs hit 35 degrees, I opened my display case to find the head of one 1/8 scale figure tilted 15 degrees. I put it in the refrigerator for 30 minutes and straightened it by hand, but fine wrinkles appeared at the neck joint. Since then, when leaving the room in summer, I set the air conditioner timer before going out.

The speed at which you fill display cases reveals your taste

My first display case filled in six months. The second took one year, the third took two years. The slowdown wasn't due to wallet constraints but rising discernment. Early on, I couldn't distinguish between "want to have" and "must buy." Now I only buy figures that, the moment I hold them, immediately conjure where in which shelf I'll place them.

Leaving empty spaces is also strategy. Reserving a spot for a pre-ordered figure arriving in six months prevents impulse purchases in the interim. I operate each shelf on a "two permanent members + one rotating member" system. The rotating member changes monthly, giving boxed figures a turn in the display case.

When display cases fill up, there are two options: add more cases or reduce figures. I expanded to a third case, but resisted a fourth. The door-not-closing issue was one problem, but more importantly, I felt that "three display cases' worth defines the outline of my taste." Since then, when I buy a new figure, I sell an existing one secondhand. With the total fixed, each individual figure has become more precious.

FAQ

How many 1/7 scale figures can fit in one shelf?

Physically, up to five will fit, but the aesthetic limit is three. With four, back-row figures get blocked by the front row and faces are half-hidden. From five onward, bases overlap and each figure's silhouette gets muddled. Even if it looks fine in photos, if you must remove the front row to touch the back row when opening the glass door for maintenance, it's already overcrowded.

What LED strip color temperature should I choose?

If your collection has many warm-toned characters (blonde, brown hair), I recommend warm white (3000K); if many cool-toned characters (silver, blue hair), cool white (6500K). If uncertain, neutral white (4500K) is a safe middle ground. Smart LEDs with adjustable color temperature seem convenient, but in practice you rarely change them after the initial setting.

Which is better, acrylic cases or glass cases?

Acrylic is light and affordable but becomes cloudy with surface scratches after three years. Glass is heavy and expensive but maintains transparency after ten years. Acrylic suits desktop small figures, glass suits floor-standing scale figures. Long-term, glass is more economical in terms of replacement costs.

Is it okay to place a display case near a window?

Not only direct sunlight but also wall-reflected indirect light will fade figure colors within five years. Position at least 1m from windows, and if possible, apply UV-blocking film to the inside of the glass door. In summer, sealed rooms exceeding 35 degrees can deform PVC figures, so I recommend setting an air conditioner timer when leaving for extended periods.

Display cases are not containers for figures, but frames that reveal taste. How many to place, what light to use, at what height to position them—all are choices. When those choices accumulate, the sentence "I am someone who likes these things" becomes visible beyond the glass. I hope good encounters find your display cases today as well.
