The b-Vibe Flex Ring 8 is a manual, figure-eight cock-and-ball ring made from hand-poured ultra-soft liquid silicone. Its two connected openings are designed to sit around the shaft and scrotum at the same time. The maker and store model is BV-167.

The 23.5 mm and 30 mm figures describe the relaxed inner openings, not a universal fit or a recommended body measurement. The two openings have different roles in the connected figure-eight design; they are not two interchangeable sizes of a single-shaft ring.
Choose by format and fit
This design surrounds the shaft and scrotum together. If you want a different figure-eight profile, compare the b-Vibe Flex Ring Shaft. For a single-opening design, compare the b-Vibe Flex Ring Delta or the b-Vibe Flex Ring Loop. Browse cock rings and ball toys for additional materials and opening styles.
Before choosing, read how to measure for a cock ring and how to compare fit, style, and safety. A flexible ring should feel secure without pain, numbness, coldness, or marked color change. Stretchability does not make an opening suitable for every body.
Safer-use boundaries
- Read the directions supplied with the received product. Inspect the ring before every use. Do not use it if the silicone is torn, cracked, sticky, swollen, permanently distorted, or otherwise damaged.
- Use only when you can remove it promptly. Do not sleep in it or place it where removal would be difficult. If the package gives a shorter time limit, follow that limit.
- The International Society for Sexual Medicine notes that most manufacturers warn against wearing a constriction ring longer than 30 minutes. Remove it immediately for pain, numbness, or coldness.
- If swelling prevents removal, seek emergency treatment immediately. Do not keep pulling or add another constricting device.
- This product is not contraception, does not prevent sexually transmitted infections, and is not a treatment for erectile dysfunction or another medical condition.
Cleaning, lubricant, and storage
Follow the care directions on the received package. The exact maker page describes the silicone as easy to clean but does not publish an exact soap, boiling, dishwasher, bleach, alcohol, or sterilization method for model BV-167. Do not infer one. Clean before and after use, rinse away allowed cleaner, let the ring dry completely, and store it away from sharp edges, heat, and incompatible materials.
If lubricant is used, choose a product whose label confirms compatibility with silicone; water-based lubricant is the conservative default when the package does not specify otherwise. Review the cleaning and storage guide. b-Vibe lists a one-year limited warranty against defects in workmanship or materials; keep the receipt and follow the maker's current warranty process for a claim.
