The Dungeon is ideal for housing a complete card collection. It holds several deck boxes, playmats, accessories and, of course, a huge number of single cards (even protected in bigger toploader sleeves). The closing mechanism is subtle but strong thanks to an ingenious design that keeps the box safely closed even when it is fully loaded. The box’s premium Nexofyber+ outside material shares the elegant look of all Convertible products. Compatible not only with the rest of the product line but also with most boxes and solutions available on the market.
