The Vixen Extenders are hollow silicone dills with a stabilizing ring attached to the base. They are intended to be used by people with ED or simply to add girth and length to what you've already got!
These extenders are made of Vixen Creations' excellent medical grade silicone, and in order to function well, they must fit closely. (See the "internal" measurements below!) Just a word of caution, they do not stretch very much, so choose the size that fits you best. We love the design of the cock ring at the base of the toy. It's stretchy enough to be functional, but wide and sturdy enough to provide support while it's being used, um, rigorously.
