Product Description

A 21-sided die with 14 faces that come in parallel pairs and 7 faces that are not paired with a parallel face. These 7 faces lie on a middle band with heptagonal symmetry. When the die rests on one of these 7 faces, what you see from above is an edge.  The rolled value is the 2-digit number written across the edge.  

The middle band faces are numbered {01, 31, 41, 51, 61, 71, 92} which together generate the numbers {13, 14, 15, 16, 17, 19, 20}. The remaining 14 faces are numbered {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 18, 21}.

The faces numbered 6 and 9 are adjacent with different orientations so you can distinguish them.  How you assign them is up to you.

These are proably not fair dice, but they are designed so that the height is roughly equal to the diameter and the face areas are roughly equal.
