"White" Single Polyhedral 100-Sided Die (D100 Die) | Solid White Color (45mm) Black

Pick a number between 1 and 100... NO! Roll this ball that somehow has sides and it will select a number for you!

Actually, this thing rolls pretty well and as long as you can look over the top of it you will be able to see the rolled number pretty well. 

Great giant die with a tiny price.
