When placing your order ensure that you have selected the correct size ring for you - 40mm, 44mm, 48mm or 52mm diameter. We can supply individual rings but due to their nature we cannot exchange incorrectly sized rings.

To measure for a cock ring - using a fabric tape measure, place it behind your balls and around the top of your cock, close to your body. Once you have this measurement you then need to divide it by 3.14 to give you the diameter. Remember never to wear a cock ring which is too tight for you, it could cause circulation problems.
