The Sport Fucker Slinger Ring is a combo product made from super stretchy TPR. It is a c-ring and ball stretcher that is so easy to put on and take off because the material is very stretchy.
The design offers great comfort and superior contact because it has a large footprint. It remains light because of its thin tube walls. Even though the walls are thin, it does not lose grip and constriction because the material is strong.
If you are a well endowed male, you will love the stretch and flexibility.
