Rectangular Pokémon Card Box Built for Serious Collectors

Got a growing collection that a small pouch can't handle? The Rectangular Pokémon Card Box gives you real capacity — up to 400 cards in a slim, structured case that lays flat and opens wide. The full-length zipper keeps everything locked in during transport, and the rectangular shape means cards sit upright and organized, not jumbled. Take it to a card swap, a tournament, or just keep it on your desk as your go-to storage for your active collection.

What sets this case apart is the combination of size and portability. At 30 × 12 × 8 cm and 350g, it holds significantly more than a standard card holder without becoming bulky. The PU exterior is smooth, wipe-clean, and available in three distinct Pokémon designs — Red Poké Ball, Purple M, and Purple Four Monsters — so it looks as good on a shelf as it does in a bag.

Rectangular Pokémon Card Box — Common Questions

▶ How many sleeved cards does it actually hold?

The Rectangular Pokémon Card Box holds up to 400 cards. With standard single sleeves, you can comfortably reach close to that capacity. Double-sleeved cards will reduce the count slightly — expect around 300–350 depending on sleeve thickness.

▶ Is the zipper strong enough for daily use?

Yes. The full-length zipper is designed for regular open-and-close use and runs the full length of the case for a secure seal. It keeps cards from shifting or falling out even when the case is carried at an angle in a bag.

▶ Does it work for other TCGs like Magic or Yu-Gi-Oh!?

Yes. The interior dimensions fit standard trading card sizes used across most TCGs, including Magic: The Gathering and Yu-Gi-Oh!. The Pokémon artwork is on the exterior only — inside, it's a universal card storage case.
