These 16mm green dice are numbered 1 to 6 with alien symbols etched into the surface of the dice and painted red or black. When the dice are charged (under light for some time) and the lights go out, watch as these dice eerily glow in the dark! A large alien face is etched into the side where the 1 pip, the "ace," would traditionally be located. Other symbols include alien eyes, and UFOs. Use these alien dice to play your favorite dice and board games or create your own unique game.
