The Colt 3-Ring pack contains all you need to up your potential for perfect satisfaction- it holds 3 soft, stretchy rubber rings in sizes running from 1 1/4 inches to 2 inches with a perfectly midsized version in between, one for almost every man. Cock rings work by keeping blood in the penis for a firmer, longer lasting erection, effectively drawing out playtime. Looped under the testicles, one of these wide rings also add a supportive feel and help keep sensation under control. Use a good water or silicone based lube in combination with the Rings to keep the pliable, plush rubber material at its best.
