Polyhedral dice are standardized 7-die sets used in tabletop role-playing games (TTRPGs) including Dungeons & Dragons and Pathfinder. A standard set consists of D4 (tetrahedron), D6 (cube), D8 (octahedron), D10 (pentagonal trapezohedron), D% (percentile tens), D12 (dodecahedron), and D20 (icosahedron), manufactured in standard 16 mm to 22 mm millimeter heights based on Platonic solids.

Toploaders are rigid polyvinyl chloride (PVC) protective holders designed to store collectible trading and sports cards. Sized at 3×4 inches (76.2×101.6 mm), toploaders are classified by a standardized 'Point' (pt) thickness scale ranging from 35pt (standard paper cards) up to 360pt (thick memorabilia, patch, and relic cards), where 1 pt equals 0.001 inches (1 mil).
