Sport Fucker has created a line of rings that give you the best of silicone with things you love about metal. Their Fusion Rings feature a revolutionary super soft liquid silicone exterior with metal rods embedded within to provide tension and support in just the right places.
The Overdrive Fusion Ring has an arc of metal embedded in each half, giving it a static shape, like a metal ring. Between the two halves it's only stretchy silicone.
The Fusion Rings come in three sizes: Regular has a 32mm inside diameter, Large has a 37mm diameter, and X-Large has a 42mm diameter.
