Super Soft C-rings have a broad ring surface, for comfort and straightforward use. The soft silicone material stretches making it easy to pull open and slide onto your body. A c-ring holds the testicles down and keeps the testes from contracting thus slowing down ejaculatio. It can be used either as an erectile function application or for edging. Always made with 100% Tantus Ultra Premium silicone, making it sit gently on your body and give you peace of mind.
