Product questions
What cards fit in this deck box?
Ultimate Guard lists this Squaroe for standard- and Japanese-sized trading cards. It holds up to 100 double-sleeved cards, 120 single-sleeved cards, or 210 unsleeved cards.
Is this a deck box or a collectible display piece?
It is both. This product is a functional Ultimate Guard deck box with secure closure, but the fully printed Mind Flayer art also makes it a collectible Dungeons & Dragons accessory.
Will every 100-card deck fit the same way?
Not always. Ultimate Guard notes that the stated capacity is based on its own sleeves, so thicker sleeves or different brands can change the fit.
Add a Mind Flayer favorite to your deck storage lineup with a Squaroe that looks sharp on the table and protects your cards between games.
