The patented soft comfortable ring stretches easily to fit at the base of the penis gently maintaining arterial flow and controlling venous outflow thereby sustaining a firmer erection. Confidence Rings fit all sizes and are available in two strengths, firm and regular and last for about 6 months. The Confidence Ring was developed and tested over a 4 year period and has a 90% success rate in holding erections. The rings are made from a special patented silicone formula that is 50% softer than latex and never gets in the way during intercourse. A unique feature is the built in memory which adapts the ring to the circumference of the penis during the first time of use. This pack contains 1 Regular and 1 Firm. We recommend trying one of each with your first purchase.
