The dungeon is ideal for storing a complete card collection. It accommodates several stack boxes, playmats, accessories, and of course, a large number of individual cards, even protected in larger toploader sleeves. The closure mechanism is subtle yet strong, thanks to a clever design that keeps the box securely closed even when fully loaded. The high-quality Nexofyber+ exterior material of the box has the elegant appearance of all Convertible products. It is compatible not only with the rest of the product line but also with most boxes available on the market. Warning: Not suitable for children under 36 months.
