All of our Jollies are made from 100% platinum grade silicone. The Jollie is the same shape as the Jollet and Groove at the tip and hump. The Jollies amazing feature that stands out is the handle. The handle can be used to hold a bullet vibe, and can be used to hold and help control and wiggle. Email us at email@example.com if you'd like to create a custom Jollie.
