The Potenz Duo Rings are made from Medical Grade Silicone. They will not crack, peel, or deteriorate like other cock rings. And their flexibility is OUTSTANDING. The larger ring goes over the top of the shaft and stretches back behind the testicles. The second ring (optional in the opinion of some of our staff) goes on the base of the shaft. The rings work together to extend the life of erection, increase the firmness of the erection and change the sensations of sex dramatically. Every guy who has tried these (especially the big one) sings their praises (just remember a little trim prevents owies when removing!)
