The Tantus Uplift C-Ring Cock and Ball Sling Onyx is a premium silicone accessory that combines two stretchy rings into one sleek, ergonomic shape. Engineered to lift the shaft and cradle the scrotum separately, this C-ring cock and ball sling delivers firm support without pinching or slipping, so wearers can enjoy longer, more confident sessions. Its muted Onyx finish keeps the look understated, while the hygienic platinum silicone ensures a smooth, body-safe feel every time.

• Dual-ring structure separates shaft and balls for targeted lift
• Light, forgiving stretch molds to your anatomy without excessive pressure
• Platinum-grade silicone – hypoallergenic, phthalate-free, and non-porous
• Onyx color hides signs of wear and stays discreet
• Easy to rinse clean with mild soap and warm water

Unlike hard plastic rings, the Tantus Uplift uses just the right amount of elasticity. The two rings work independently: the narrower top ring grips the base of the shaft for extra firmness, while the wider lower ring cradles the scrotum without digging in. This split design helps prolong erection by slowing blood flow out, which can lead to heightened sensation and a more controlled finish. The C-ring cock and ball sling stays put during movement, so it’s suitable for solo play, partner intimacy, or extended wear under clothing.

1. Apply a drop of water-based lubricant to the inside of both rings for easy sliding.
2. Stretch the larger bottom ring first and guide the scrotum through, then pull the shaft through the smaller top ring.
3. Adjust until the sling sits comfortably behind the testicles and the upper ring rests at the base of the shaft.
4. Check that nothing feels pinched or overly tight; the ring should feel snug but never painful. Remove after 20-30 minutes of use.

Silicone is non-porous and odor-resistant, making upkeep straightforward. Wash the C-ring cock and ball sling with warm water and mild soap before and after each use. For a deeper sanitization, boil it for 3-5 minutes or place it on the top rack of a dishwasher without detergent. Store it in the included lint-free pouch away from other silicone items to prevent surface reactions. Only pair with water-based lubricants – silicone lubes can degrade the material over time.

We found the Tantus Uplift C-Ring Cock and Ball Sling remarkably comfortable for all-day wear. The silicone has a velvety matte finish that doesn’t grab hair, and the dual-ring ergonomics really do stay in place without constant readjusting. During testing, the gentle compression added noticeable firmness without any numbing, and the Onyx color stayed pristine after multiple boil cycles. If you’re new to cock rings or want a reliable, no-fuss sling that prioritizes safety and comfort, our team recommends this model without hesitation.
