Black soft phthalate-free vinyl.
Not so big but very very nice with the multiple foreskin-skin-skin-ribs that will drive you nuts when you devour this one, even when it's not huge.
As extra it has a suctioncup so you can stick it to a smooth surface so you can better ride on it.
Lenght: 20 cm. (8 inch), Diameter 5,5 cm. (2,25 inch)
