Ultimate Guard's Boulder 100+ Solid is a durable and reliable deck box made from fully opaque material and features a solid surface without the soft-touch feel of the classic Boulder. The deck box, made in Germany, holds 100 double-sleeved cards in Ultimate Guard sleeves* from trading card games like Magic: The Gathering, Pokémon, Lorcana, Flesh and Blood, Yu-Gi-Oh!, Riftbound, or One Piece. Designed to combine with all Ultimate Guard mass storage boxes, Boulders fit especially well into Arkhive, Superhive, and Flip'n'Tray boxes.
