UP your game with Gravity Dice! We utilize the most advanced 3D modeling and simulation to bring you perfectly balanced dice. Through complex model algorithms we found a balance between great weight, center of gravity and exceptional style. Made from anodized, aircraft-grade aluminum with laser-etched dots and logos, while the chamfered edges and perfect center of gravity make them ideal for extended rolls. Each die measures 0.63” (16.01 mm.) and fits in a hard-anodized, laser-etched case with magnetic closure.
