Rimz BIG Ring by OxBalls

Rimz BIG Ring by OxBalls is a cushioned, oversized cock ring made from ultra-soft FLEXtpr™ that fits larger sizes comfortably while maintaining firm blood-flow restriction. Its dual comfort lips prevent rolling and pinching during extended wear. Ideal for men seeking reliable erection support without irritation.

Design and build

Rimz BIG Ring by OxBalls is engineered for men who need a larger fit without sacrificing comfort or grip strength. The body-safe FLEXtpr™ material is plush and forgiving, stretching easily over the penis or scrotum then settling into a secure, cushioned hold. Its 20 mm inner diameter accommodates bigger sizes, while the dual comfort lips—a design feature that sets it apart from standard stretchy cock rings—prevent rolling, pinching, or skin irritation during hours of wear.

The ring weighs just 28 grams but delivers substantial pressure for reliable erection support and blood-flow restriction. Its stackable design means you can pair two rings for customised ball stretching that adds thrilling intensity. Unlike rigid metal or thin plastic alternatives, this soft material adapts to your body shape, making it practical for all-day wear without adjustment or discomfort.

What stands out

• Dual comfort lips: These prevent the rolling, pinching, and digging that plague cheaper rings, keeping you comfortable even after extended sessions.
• Larger 20 mm fit: Many men find standard rings too tight; this one stretches to accommodate bigger sizes while maintaining a secure, supportive grip.

• Stackable design: Layer two rings together for customised ball stretching that delivers an intense, pleasurable sensation you control entirely.

Finding your size in a stretchy cock ring

Measure your erect penis girth at the base where you plan to wear the ring. The Rimz BIG's 20 mm inner diameter suits men with a girth of roughly 50–65 mm when relaxed—it stretches significantly, so if standard rings feel too tight, this size is likely right for you. Start by applying a small amount of water-based lubricant to your penis, then gently stretch the ring and roll it on. You should feel a snug, even pressure around the entire circumference with no pinching or excessive tightness.

Once on, adjust your position until the ring sits comfortably—typically at the base of your penis or around the scrotum, depending on your preference and intended use. If you're stacking two rings for ball stretching, put the first on your penis then roll the second onto your scrotum, experimenting with spacing to find what feels best.

Care and storage

Wash the ring with warm water and mild soap after each use, then pat dry and store in a cool, dry place away from direct sunlight. The FLEXtpr™ material resists staining and discolouration, but avoid prolonged contact with oils, lotions, and petroleum-based lubricants. Do not store in airtight containers; allow air circulation to prevent moisture buildup and odour.

Background reading

Cock rings work by restricting blood flow out of the penis, which helps maintain erections longer and can increase sensitivity and firmness. They come in various materials—silicone, metal, leather, and elastomer—each with different properties. Learn how different rings perform and which suits your needs by reading our guide on Cock Rings.

What to expect

The moment you slip the Rimz BIG on with lubricant, you'll feel the soft FLEXtpr™ grip snugly around your penis or scrotum. Within minutes of wear, most users notice their erection becoming noticeably firmer and lasting longer than usual. The dual comfort lips sit flush against your skin, so there's no rolling, digging, or need to adjust throughout your session.

First-time users often find the sensation unfamiliar but pleasurable—a gentle, sustained pressure that heightens sensitivity and makes orgasm feel more intense. If you stack a second ring for ball stretching, expect an added thrilling tug that ranges from subtle to intense depending on spacing and how tight you position each ring. The material adapts to your body temperature and shape within the first few minutes of wear.

Cleaning is straightforward: warm water and soap remove any residue, and the material dries quickly. Unlike metal or rigid plastics, the FLEXtpr™ won't mark your skin even after hours of wear, and it resists odour and discolouration over time. Most people find it comfortable enough for extended sessions without irritation or circulation issues.

The ring performs best when you use water-based lubricant for easier application and removal. Wear time typically ranges from thirty minutes to several hours depending on comfort and personal preference. If you find standard rings too tight or uncomfortable, the larger diameter of the Rimz BIG often eliminates those problems while still delivering reliable pressure and support.
