Groove Edge Silicone Ring - Black. Available in whole sizes 8, 9, 10, 11, 12, 13, 14. At first glance, our Edge ring looks just like a traditional, metal ring. However, our flexible silicone and breathable inner grooves keep you feeling comfortable while still looking good. Designed with a beveled edge that can go from the boardroom to the ski slopes.

Made from 80 durometer medical grade silicone, Groove is the first and only active ring to be liquid poured. This means fine detail and perfect design with little to no mold marks or flaws. Groove silicone is resistant to most common chemicals including gasoline, oil, diesel, & household cleaning products. Groove is also non porous, non conductive, heat resistant, and hypoallergenic.

Groove is two rings in one. We first began with the inner ring. Firmer and full of infinity grooves that allow the ring to breathe. The inner ring also features an inverse arch know as a comfort fit that lessens the contact with your skin.
