The Ma-Sai series onacup have the outer appearance of a horn. This slight tapered curve is designed to help the holding of the onacup during use. The name of the onacup reflect the the overall theme of the item. Zebra is more mellow as the beginning of the internal tunneling is lined with thin ribs and transitions into a thicker ribs section and ends with a nubs chamber.
This version is the Zebra onacup.
