The DuroRing cock ring is a heavy penis ring used to keep the blood trapped in your penis after pumping or jelqing sessions to maintain your full penis in an expanded state as the tissue heals from expansion.

The DuroRing is the last cock ring you will ever need. It comes with a 90 Day replacement warranty and will not stretch out of shape or break after long term use because they are not manufactured like most other silicone cock rings on the market.

The DuroRing stretches up to 90mm is hypoallergenic and comes in three inside diameters ranging from 16mm, 18mm & 20mm or as a complete set (choose in the drop down menu).
