Absolute Precision 16mm 10 Sided D5 Dice numbered 1-5 twice, with inked numbers. 

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.
