The Enhancer Cockrings are 100% silicone, durable, thick and firm; yet soft to the touch and stretchy for comfort during wear. Three rings, each of a different size, are individually packaged within each set. These rings may be used as a traditional cocking, around the testicles, as harness rings, and more! Please clean before and after each use with toy cleaner and enjoy with water-based lubricants.
