Puro Clear Stretchy TPE Cock Ring | Raeven CORE

The Puro Clear Stretchy Cock Ring from Raeven CORE is a simple, non-vibrating penis ring made from flexible TPE.

Its single-ring design is listed for placement around the base of the penis. The TPE stretches during fitting, while the fully manual format requires no batteries, charging cable, buttons or vibration settings.

Puro is a straightforward option for customers who prefer one flexible ring rather than a multi-size pack or a connected penis-and-scrotum design. However, its internal diameter and maximum stretch range are not currently stated. These measurements should be checked before use rather than assuming the ring will fit every size.

For three separate coloured rings, compare the Do-Nut 3-Pack Multi-Coloured Cock Rings.

For a connected silicone design listed for placement around both the penis and scrotum, compare the Asgard Stretchy Silicone Triple Cock Ring.

Puro is also included in Raeven’s Multi-Size Cock Ring Starter Set, alongside Asgard and three measured Ironn silicone rings.

Sizing, Use, Lubrication and Care

Measure the area around the base of the penis where the ring will sit. Compare that measurement with Puro’s internal diameter and safe stretch range once Raeven publishes them. Flexible TPE can make fitting easier, but it does not remove the need for appropriate sizing.

Follow the supplied product instructions when stretching or rolling the ring into position. Do not force it over an area where it feels painful or difficult to move, and confirm that it can be removed easily before continuing.

The ring should feel secure but must not cause pain, numbness, tingling, coldness, unusual swelling, trapped skin, difficulty during removal or a strong colour change. Remove it immediately if any of these warning signs occur. Keep sessions short and never sleep while wearing a cock ring.

A small amount of Slide Water-Based Lube 50ml can reduce pulling during fitting and removal. Use only enough to reduce friction, as excessive lubricant may cause the ring to move out of position.

Clean Puro before and after use according to its TPE care instructions. The existing Raeven Cleanse Essential Sex Toy Cleaner does not specifically list TPE among its confirmed compatible materials, so compatibility should be checked before applying it to Puro.

The product page currently says to rinse and dry the ring, but it does not confirm whether Puro can be fully submerged, washed with soap, boiled or treated with heat. Do not use an unconfirmed cleaning or sterilisation method.

Allow the ring to dry completely before storage. Store it separately from other products if the manufacturer’s TPE care instructions recommend material separation.

Avoid rubber bands, cable ties, string, washers and other household substitutes. Raeven’s homemade cock ring guide explains why improvised objects may tighten unpredictably, pinch the skin or become difficult to remove.
