Gundam Display Box Guide: Acrylic Cases That Keep Kits Clean

A Gundam display box is a clear case, often acrylic, that keeps dust off a finished kit while you can still see it from every side. Pick one tall and wide enough for the kit as posed with its stand, and keep it out of direct sun, because light damage to plastic builds up over time.

What a Gundam display box is for

A Gundam display box protects a finished build on a shelf. Dust settles into panel lines and the gaps between armor parts, and it is slow to clean out once it is there. A closed case keeps most of it off and shields the kit from knocks.

A case does a different job from a stand. A stand, such as Bandai’s Action Base, holds a kit in a mid-air pose; our guide to Gundam stands and Action Bases covers sizes and adapters. A case goes around the kit, and a tall enough case can hold a kit on its stand, so you get both.

The Canadian Conservation Institute (CCI) notes that clear plastic panels are usually acrylic, polycarbonate or polystyrene, and that plastic panels are common for enclosures. Product listings name the material, so check it before you buy.

Sizing a display case for your Gunpla grade

A display case for Gunpla should fit the kit as it will stand, not the size printed on the box. Wings and long weapons add width, and a stand arm adds height. Use the kit’s grade and scale as a first guide, then measure.

Leave a gap between the kit and every panel, so nothing rubs when you lift the lid. For how big each grade builds up, see Gunpla scales explained.

Sunlight, UV and lights near a display case

Light is the main long-term risk to a kit in a case. The Library of Congress says light damage is cumulative and in most cases cannot be reversed, and that sunlight is generally kept away from light-sensitive items. The CCI adds that UV light damages plastics, and that for some plastics visible light causes deterioration too.

A clear case is not a full UV shield. In the CCI’s note on UV filters, plain glass blocked only about 26% of UV, and most clear plastics give some UV protection, mostly to protect the plastic itself. Conservation-grade UV-filtering acrylics cut far more. If a case will sit near a window, a UV-filtering panel is worth asking about.

If you light a case, keep it dim and cool. The CCI suggests keeping light on plastics low, never above 150 lux, and avoiding hot lights. Our page on LED units for Gunpla covers lights made for specific kits.

Where to place a display case at home

A good spot for a display case is a cool, shaded shelf. The CCI says higher temperatures speed up the deterioration of plastics, so keep cases away from heaters and sunny windowsills. It also notes that plastics are more brittle when cold, so let a kit warm to room temperature before you move its parts.

Strong, level shelves matter for large kits. A big kit on its base weighs more than a small one, and the case adds its own weight on top.

Display case, stand or open shelf

Each way of showing a kit has a trade-off. Airfix suggests stands, wall brackets and dioramas for finished models. With Gunpla, a case can sit around any of them.

1. Open shelf: easy to reach and repose, but dust settles quickly.
2. Stand on a shelf: dramatic poses, still open to dust.
3. Case with a stand inside: poses plus protection, at the cost of a bigger footprint.
4. Diorama in a case: the most work, and a scene that stays clean.

Finish a kit before it goes behind clear panels, since every nub and scratch shows: see our guides to top coats and the rest of the Gunpla tools worth owning. Long, low models such as model ships need a case sized to the hull rather than a tall cube.
