About this Product
A sphericon is usually described as solid with a single continuous face and two edges. It rolls by wobbling along that face and associated edges, resulting in straight-line motion. This is a naked version of the Sphericon that just keeps the essential : the two edges that are needed to roll - this sphericon will work exactly as any other. It uses a small amount of material for decent prices in a large 10 cm version.
