Ultimate Guard: Boulder 100+ Synergy - Blue/Red

Ultimate Guard's Boulder 100+ Synergy is a durable and reliable deck box featuring our popular soft-touch surface on both the semi-transparent top and the solid base. Despite its secure closure, the Boulder 100+ Synergy is easy and convenient to open and 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.
