Based on military Challenge Coins, these three double-sided metal coins replace an entire 7-polyhedral set for RPGs (D&D, etc), you get a D4, D6, D8, D10, D12, and of course the D20. Now available with a soft plastic display case with an EVA foam insert to hold coins in place. Simply give the coin a spin (like a top) then stop it with a pencil (or anything else) to mark your result, never lose a die under the couch again!
