b-Vibe Flex Band 30 mm Silicone Cock Ring

The b-Vibe Flex Band 30 mm is a silicone cock ring made for people who like a close, firm hold. It's the snug option in the Flex Band line, but because it's hand-poured from ultra-soft liquid silicone, that small opening stretches easily over the body and settles into a secure fit. The seamless, smooth band is simple, comfortable and easy to keep clean.

Why a liquid silicone cock ring suits a snug fit

A small ring in hard material can pinch and be awkward to get on. b-Vibe solves that by pouring the Flex Band by hand from ultra-soft liquid silicone, which is very elastic. It stretches wide to go on, then pulls back to a steady, even pressure. The surface feels close to skin, and the band is seamless, with no ridge from a mould line to rub or chafe. Silicone is non-porous, so it washes clean easily.

Sizing: is 30 mm right for you?

The "30 mm" in the name is the size class; b-Vibe lists the inner diameter as 31.5 mm, with an outer length and width of 49 mm. That's on the tighter end for most wearers, especially if you plan to wear it around the shaft and balls together. To check, wrap a strip of paper or a soft tape measure around the base of the penis when soft, and around the base and behind the balls for a full fit. Divide the circumference by 3.14 to get the diameter. If your soft measurement is close to or above 31.5 mm, expect a very snug hold, which is exactly what some people want. If you prefer a lighter feel, look at a larger size. Our cock ring size guide walks through this in more detail.

Putting it on and taking it off

Put the ring on while soft. A drop of water-based lube inside helps it slide. For a shaft-only fit, stretch the band with two fingers and roll it down to the base. For a full fit, pass one testicle through, then the other, then the penis. The ring should feel snug but never painful. To take it off, hook a finger under the band and stretch it outward rather than pulling it along the skin.

Comfort and wear time

Even soft silicone needs sensible limits. Start with 20 minutes, and stay under 30 minutes at a time until you know how your body reacts. Take it off if you feel coldness, numbness, tingling or see a colour change. Because the band is smooth and stretchy, it's easy to remove quickly if you need to. If you're new to rings altogether, wear it a few times on your own before using it with a partner, so you already know what a comfortable level of pressure feels like at this size.

Cleaning and warranty

Wash it in warm water with mild soap or a toy cleaner after every use, rinse and let it air-dry. Avoid silicone lube with any silicone toy, as it can wear down the surface. b-Vibe backs the Flex Band with a one-year warranty.
