Cool Ring Black Onyx

Cool Ring Black Onyx

A classic cock ring that works. Made from liquid silicone with enough stretch to fit comfortably without feeling tight or restrictive. The material is soft — almost like an extra layer of skin around the shaft — but firm enough to do its job.

Wear it around the base of the penis to restrict blood flow slightly, which helps maintain a firmer erection for longer. Many also notice more intense orgasms when using a ring. The same stretchiness that makes it comfortable also means you can experiment with wearing it around the testicles if you prefer that sensation.

This is a manual ring — no vibrations, no batteries, no buttons. Just put it on before or during play, and take it off when you're done.

The Feeling

The silicone sits snugly without pinching. You'll feel a gentle, constant pressure that keeps blood in the penis, which translates to a harder erection that lasts longer than usual. Some describe the sensation as a firm grip that doesn't tire. During orgasm, the restriction can make the release feel more concentrated and intense.

If you wear it around the testicles instead, the feeling is more about weight and awareness — a constant reminder that adds a layer of sensation during movement or touch.

Sound Level

Silent. This is a non-vibrating ring.

Material & Body

100% liquid silicone. The inner diameter stretches from 3 to 5 cm, which covers most anatomy comfortably. The silicone is matte black, body-safe, and doesn't absorb odours.

Because it's pure silicone, avoid silicone-based lubricants — they can degrade the material over time. Use a water-based lube like Mshop Care Lube:IT instead.

Good to Know

Waterproof, so you can wear it in the shower or bath without worry. Clean with warm water and mild soap, or use a dedicated toy cleaner.

If you're new to cock rings, start by wearing it for shorter sessions — 20 to 30 minutes — to see how your body responds. Remove it immediately if you feel numbness or discomfort.
