Increase stamina and enjoy harder, longer, thicker, erections with the Stay Hard Nutz cock ring set. Made from a very strong TPE material, you can play comfortably knowing the tear-resistant elastomer won't rip on you! With its 1.7" outter diameter, it's not meant for everyone, but that doesn't mean we don't have the right for you! No Fragrences, Phthalates, Parafins, or Latex to bother your skin or cause irritation. Each pack includes 2 rings, so you can wear them one at a time or one on the shaft and the other around your balls for that tight constricting and stretching sensation.
