This D100 is AMAZING!  It weights nearly 11 ounces and is the heaviest die we've ever carried.  The numbers are raised making it very easy to stop rolling and to see which number is facing straight upward. 

A 100-sided die, or D100, invented by Lou Zocchi in 1985, is sometimes called a Zocchihedron or "Zocchi's Golfball." Rather than being a true 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.
