The Boulder 100+ is a durable and reliable deck box, featuring officially licensed art from Magic: The Gathering's "Edge of Eternities" set. Despite its secure closure, the Boulder 100+ is easy and convenient to open and holds 100 double-sleeved cards in Ultimate Guard sleeves. Designed to combine with all Ultimate Guard mass storage boxes, Boulders fit especially well into Arkhive, Superhive and Flip'n'Tray boxes.
