Groove "Thin" is designed for the person looking for a little less bulk but the same great function. Like the Groove Original, the Thin is a unisex ring that looks great no matter who is wearing it. Groove is the only active ring on the market to offer breathability. Because of this, Groove is to be worn snuggly on your finger which keeps your ring from catching and grabbing on things in your environment.

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.
