Wearing a c ring can create larger, harder erections, and intensify the sensation of a males orgasm. The Tantus Super Soft C Ring is a redesigned version of our classic ring. We used the same Ultra Premium Silicone, but with a stretchier, softer texture to make it easier to put on even with an erection. Wear it around both the penis and testicles for the most intense effect. Unstretched Diameter 1.5 inchesStretched Diameter 4.75 inches
