Penis and Testicle Ring CRAZY BULL Nestor — ergonomic design, single-piece silicone/resilient material

CRAZY BULL Nestor is an ergonomic penis and testicle ring designed to provide gentle constriction and reliable support. The single-piece, soft and stretchy silicone/resilient material fits around the base of the penis and behind the testicles to help maintain erection firmness and offer enhanced sensation. Its thicker profile is intended to anchor securely around the shaft while gently pulling the testicles down, producing a swinging and swaying feeling during movement. The resilient construction is body-safe and suitable for repeatable use in solo or partnered play.

Advantages

The one-piece design combines elasticity with a snug fit to deliver consistent constriction without separate parts. Soft, skin-safe material reduces friction and increases comfort during extended wear. The thicker ring profile provides stable positioning at the base of the penis and behind the testicles, supporting longer-lasting erection firmness and heightened tactile feedback. An easy-grip section on the ring helps maintain control and positioning throughout use.

• Users seeking erection support and improved duration
• People who want gentle testicle stretching and enhanced sensations
• Solo sessions where manual control of stimulation is preferred
• Partnered intercourse for increased firmness and feedback

How to use

Before first use and after each use, clean the ring with warm water and mild soap or a toy cleaner and dry thoroughly. Apply a small amount of water-based lubricant to the inner surfaces and the base of the penis for easier application. Gently stretch the ring and slide it to the base of the erect penis, positioning the secondary loop behind the testicles if desired. Adjust placement for comfort: the ring should feel snug but not painfully tight. Monitor for any numbness or discoloration and remove immediately if discomfort occurs. After use, wash and store the ring in a dry, cool place away from direct sunlight.

Usage recommendations

Use only water-based lubricants with silicone-based items to avoid material degradation. Limit continuous wear to recommended safe intervals, check circulation regularly, and discontinue use if pain, prolonged numbness, or significant color change occurs. If you have circulatory, neurological, or prostate concerns, consult a healthcare professional before use.
