The ultimate fair dice allowed by Mother Nature (i.e., mathematics)! The d120 is based on a polyhedron known as the disdyakis triacontahedron. Each face is a scalene triangle. These dice are perfectly numerically balanced, with the same sums for numbers around vertices of the same type.

At 2” in diameter and weighing 1/3 lb, these unique dice will fascinate students and can be used to spark discussion of a range of topics relating to geometry, numbers, and statistics. They can also be used with other dice in a variety of dice games for practicing arithmetic skills. The d120 can also be used as a dn, where n is any proper factor of 120, including all of the dice in a standard seven-dice polyset. Colors may vary.
