This case can be used for dice display and storage for Dungeons and Dragons, Pathfinder, Call of Cthulhu, etc. I've never used it (you can see the original shipping box and packets of silica gel I never removed in some of the photos). The case is made from an aluminum alloy frame with 3mm clear fiberglass on either side and EVA foam to protect the dice. Each side can hold 13 sets of polyhedral dice (91 dice) for a total of 26 sets of polyhedral dice (182 dice). Exterior Dimensions: 420mm x 270mm x 50mm OR 16" x 10" x 2" Weight: 1.2kg Maximum Dice Diameter: 27mm
