Ultra PROs Foldable Tray of Rolling for Dungeons & Dragons offers a safe and aesthetic space for rolling dice. These trays are no bigger than a sheet of paper (8.5 in. x 11 in.) when flat, and utilize small magnets in each corner to easily pop up walls to keep dice under control when rolling – no bulky clasps or snaps needed! Store your dice rolling tray easily in your backpack or character folio. The Foldable Tray of Rolling is reversible! With one side a black leatherette material with a red foil Dungeons & Dragons logo, and the other featuring an inverted red leatherette with a high gloss black logo, the Foldable Tray of Rolling is the perfect addition to any gaming dungeon.
