Mystim cock rings are made of 100% surgical stainless steel.
Tips:
Never put on the cock ring on an erect penis. Start by carefully tucking in one testicle at a time and then insert the penis into the ring.
Never wear the cock ring for more than 30 to 35 minutes and always remove the ring gently if needed using a lubricant.
Finding the right size is crucial in order to guarantee the best results of your cock ring:na ring which is too small, it might lead to medical problems.
Measure the right size by wrapping a piece of non-elastic band around testicles and penis, so that the ends of the band meet on top of your penis, close to your body. Pull the band tight, so that it feels still comfortable. Mark the band on both sides, where the ends meet and measure the length in mm. Now divide this length by pi (3.14) in order to find out your diameter. We recommend repeating this measurement on some days and various day times because there might occur natural fluctuations.
Please – especially if you are new to cock rings – always chose the bigger diameter in case of doubt.
