Card sleeves are protective polymer covers manufactured in standardized millimeter dimensions to fit trading card games (TCGs) and board games. The universal matrix spans Standard Size (66×91 mm for MTG, Pokémon, Lorcana), Small/Japanese Size (62×89 mm for Yu-Gi-Oh, Cardfight Vanguard), Perfect Fit/Inner Sleeves, and Tarot Sleeves, measured in micron thickness grades (50 to 120 µm).

The 6-sided die (D6) is the most common cubic die standard. Standard board game dice measure 16 mm (5/8 inches) with indented, painted pips and rounded corners. Precision casino dice measure 19 mm (0.75 inches) with razor-sharp 90° edges, serialized markings, and flush-drilled pips filled with density-matched epoxy to minimize weight bias and maximize roll fairness.
