About this Product
The sphericon dual is two half-cylinders stuck together so that their axes are perpendicular. This shape is ideal for 4-sided dice because it lands with a face showing upward, rather than a point as with the tetrahedron. It can also be used as a 2-sided die depending on how you label the faces. I also sell numbered versions of these dice.
