How many cards can this deck box actually hold?

This Stepane box offers flexible storage: up to 230 unsleeved cards, 120 single-sleeved, or 100 double-sleeved cards. The space-efficient design means you can carry a full Commander deck plus tokens and sideboard without bulk. The 15% slimmer profile compared to typical deck boxes makes it tournament-friendly, fitting easily into bags or backpacks.

Patented viewing window: function meets display

The front of the box features a clear window that lets you showcase your most prized card or artwork without removing it from the protective interior. The window is integrated into the PU leather cover, so the box remains fully protective against impacts, scratches, and daily wear. The shock-absorbent construction keeps cards safe during travel.

Complete organization kit included

Inside the box, you'll find two adjustable dividers that let you separate cards by category, color, or deck. A mini snap card holder (archival-quality toploader) is sized specifically for Commander cards, providing a secure spot for your commander. Bonus anti-slip silicone grips are included to help you handle cards and tokens securely during gameplay or trades.

Compatibility with multiple TCGs

Designed primarily for Magic: The Gathering Commander, this box also fits cards from Shadowverse Evolve, Pokémon TCG, Yu-Gi-Oh!, and other CCGs that use standard-sized cards (63x88mm). The interior accommodates various sleeve thicknesses, including double-sleeving with standard or premium sleeves.
