These are now out of production.

This is an absolute precision 16mm 6 sided D6 dice.

The number one replaced with the Mushroom Cloud logo as pictured.

All GameScience precision dice are precision-tested and razor-edged (with sharp points!) because they have not been tumbled or sanded. To smooth down the spot on your die that is rough from being broken from the sprue, simply use hobby/automotive sandpaper. These sharp-edged dice are better than the egg-shaped round-edged imported dice because they will roll accurately.
