This is a super-safe, super-stretchy Cock Ring designed to comfortably fit all sizes and stay snug during even the wildest sexual encounter. The simple design keeps his erections stiff and strong, and by letting blood flow more slowly to the member, he'll stay harder longer and give him a powerful orgasmic release. Just stretch the ring onto the base of the penis and watch it grow for longer-lasting, more satisfying sex for both partners. 

Do-nut is designed to stay where you want it, doesn't roll, but flattens out as it stretches so it won't roll and snag your short & curlies.

Phthalate Free Pure TPR, no PVC or Vinyl.
