Collecting and care
Gundam cards are the same physical size as every other trading card we deal in, so the same storage and the same mistakes apply. This page is the practical side: what damages these cards, and what actually stops it.
Quick answer
Every GUNDAM CARD GAME card is printed at the standard trading-card size, 63 × 88 mm, the same as Pokémon, One Piece, Dragon Ball and Naruto — so one set of sleeves and rigid holders covers the whole collection. The things that damage these cards are bending, edge and corner wear from cards sliding against each other, surface scratches, and long exposure to light or heat.
The size, first
Every card in this game is printed at the standard trading-card size, 63 × 88 mm — the same as Pokémon, One Piece, Dragon Ball and Naruto. That is the single most useful fact here, because it means one set of sleeves and rigid holders covers the whole collection across every series.
What damages a card
- Bending. A card left loose in a box bows under its own stack. Stored upright and supported, it does not.
- Edge and corner wear. This comes from cards sliding against each other. A sleeve stops the sliding, which is why the sleeve matters more than the box.
- Surface scratches. Handling on a hard surface. The foil and finish that make a card look good are also what show a scratch first.
- Light and heat. Long exposure fades ink. A shelf facing a window is the usual cause, not the age of the card.
- Damp. Paper takes on moisture and the card cockles. A dry, steady room is better than a cold one.
What to store them in
Three levels, and they solve different problems:
- A sleeve protects the face and the edges from handling. This is the level that matters most, because handling is what happens every time you look at the card.
- A rigid holder or a toploader adds stiffness, so the card cannot bend. This is what you want for a card that travels.
- A binder or a box organises the collection and keeps cards from rubbing against each other. Choose one that holds the cards without pressure on the stack.
The one rule that matters
Do not store a card loose next to another card. Almost everything that goes wrong with a collection is some form of two cards touching each other without a sleeve in between, and almost every fix is a sleeve.
We make sleeves and rigid holders in this size, and they are the same ones that fit the other series we cover: card protectors. A separate guide covers what fits what.
Frequently asked questions
What size are GUNDAM CARD GAME cards?
The standard trading-card size, 63 by 88 millimetres — the same as Pokémon, One Piece, Dragon Ball and Naruto cards, so one sleeve size covers all of them.
What is the most important thing for storing Gundam cards?
Putting them in sleeves. Edge wear, corner wear and surface scratches all come from cards moving against something, and a sleeve removes almost all of that.
Do Gundam cards need a different kind of holder?
No. They are the standard size, so the ordinary sleeves and rigid holders fit them exactly as they fit any other standard trading card.
Does grading protect a card?
A rigid holder does the mechanical job of stopping bending and handling. Whether to have a card graded is a separate question, and not one we answer on this page.
