Tantus Buoy C-Ring Medium Onyx

The Tantus Buoy C-Ring Medium Onyx redefines what a silicone cock ring can do. Unlike thin, stretch-only rings, the Buoy uses a thick, plush band of 100% platinum silicone to anchor the testicles downward while maintaining a snug, comfortable constriction. This dual action helps you stay harder for longer and naturally delays ejaculation. The medium sizing and sleek onyx color make it a discreet, reliable addition to any play session.

• Dual-Action Design: Thick, soft silicone ring plus testicle anchor works together to prolong firmness and control release.
• Body-Safe Platinum Silicone: Non-porous, hypoallergenic, and free from phthalates, latex, and odors.
• Medium Fit with Onyx Finish: Ideal for average girths, providing a confident grip without turning or slipping.
• Stretchy Yet Substantial: The plush band expands for easy on/off but returns to a secure, snug hold.

Most cock rings only squeeze. The Tantus Buoy C-Ring’s thick lower band sits behind the testicles, keeping them from retracting toward the body during arousal. This delays the point of no return far more effectively than a basic constriction ring. The result is a ring that enhances both endurance and erection quality without harsh pressure.

1. Apply a few drops of water-based lubricant to the inside of the ring and to the base of the penis.
2. Stretch the ring open and slide it down to the base, ensuring the thicker section sits behind the testicles.
3. Adjust for comfort. The ring should feel snug but not painful. If discomfort occurs, remove immediately.
4. Enjoy longer-lasting play; remove after ejaculation and clean.

• Wash before and after each use with warm water and mild soap or a dedicated toy cleaner.
• Platinum silicone is dishwasher safe (top rack, no detergent) for a thorough sanitization.
• Store in a dry, lint-free pouch away from other silicone toys to prevent surface interaction.
• Compatible with water-based lubricants only; avoid silicone lubes as they may break down the surface over time.

Our team put the Tantus Buoy C-Ring through its paces over several sessions. The thick silicone felt immediately substantial yet had just the right amount of stretch for easy placement. What impressed us most was the testicle-anchoring effect—it genuinely delayed climax without that tight, pinching sensation common with thinner rings. We’d recommend this as a go-to for anyone wanting reliable, comfortable performance enhancement in a sleek, discreet design.
