Silicone C-Rings and Slings or Teardrops from Tantus are broad for comfort and safety. The Ring portion holds the testicles down and keeps the testes from contracting thus slowing down ejaculation while the teardrop portion of the ring presses back into the taint exciting all of those amazing nerve endings. The constriction of the ring portion takes orgasm from about 6 seconds to up to 45 seconds. Using our silicone to make the Sling means it wonft.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 to the emergency room. The 2in. C-Sling is our least constrictive and would be used by someone who is just starting out with rings and slings. The diameter has nothing to do with the size of your junk therefore the smaller the diameter, the more difficult the ring is to get on, but once on, the more intense it will play. For best results, apply lube to the inside of the ring, then ease one testicle through at a time before finally pulling your cock through. Safe For Your Body: Made from Tantus’ own unique formula of 100% Ultra-Premium Silicone Easy To Clean: Eco-Friendly, Hypoallergenic, Hygienic, Boilable, Bleachable and Dishwasher Safe Inner diameter: 2in.
