DICE D100 GLOW-IN-THE-DARK

A 100 sided die, or D100, invented by Lou Zocchi in 1985 is sometimes called Zocchihedron or "Zocchi's Golfball." Rather than being a polyhedron, it is more like a ball with 100 flattened planes and is designed to handle percentage rolls in games, particularly in role-playing games.

Dice react to UV light, or glow in the dark after bring held under visible light for long enough.
