About this Product
A 6-sided die based on a dipyramid (a double tetrahedron, not the dual of triangular prism). When it lies on a face an edge is up. The numbers are represented by geometric shapes (circle=1, digon=2, triangle=3, etc). Max length = 28 mm. A variation on an original design by Kevin Cook.
