Tantus Intermediate C-Ring 1.875 in. BlackSilicone 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 constriction takes orgasm from about 6 seconds to up to 45 seconds. Using our silicone to make the ring means it won't pinch or grab when sitting, walking, etc. and if things get bound up, unlike metal, you can just take a pair of scissors and easily escape rather than making a trip
