These Super Soft silicone c-rings from Tantus are broad for comfort and safety. A c-ring holds the testicles down and keeps the testes from contracting thus slowing down ejaculation.
The Super Soft Ring is stretchier than the standard Tantus C-rings, so it is easier to put on. Great for beginners, too. Last but certainly not least: you don't have to put it on before an erection occurs; the silicone is stretchy enough you can put it on anytime.
Unstretched Diameter: 1.5", Stretched Diameter: 4.75"
