The Xplay 3 Pack Silicone Thin Wrap Ring includes the 9", 12" and 15". Using a special moulding process, our premium silicone material is finished with an ultra-premium silicone spray finish that reduces hair grab. These babies can provide both a gentle or aggressive level of restriction by simply adding or reducing the number of wraps. On each package, you will find an approximation of the wraps attainable for each cord length to achieve functional restriction. Of course, the longer the ring, the more tension range available. It simply comes down to what you are looking to achieve in the moment.
