Manufactured by Steve Cormack, the 3/4 inch polyester resin die has rounded corners and weighs 12.8 grams. The outer shell is continuous, with no seam. A lead weight is hidden below the surface of the die. When rolled, about 65% of the time, it will stop rolling with the weight lowermost, and your desired number uppermost.
Please indicate your choice of 1 or 6 uppermost.
