The Earl is a luxury cock ring, crafted from surgical stainless steel with a sophisticated brushed finish. This erotic piece of jewellery enhances and prolongs erection and orgasm. The smooth steel offers pleasurable heft to its constraint and is ideal for temperature or electrostim play. Please note this ring is a fixed diameter, available in two sizes: 48mm and 51mm. Measure for the correct size by wrapping a string or non-elastic band around the testicles and base of shaft. Pull the band so that it is tight but comfortable. Mark the band on both sides, where the ends meet, and measure the length in mm. Divide this length by pi (3.14) in order to find out your diameter. We recommend repeating this measurement on some days and at various times as natural fluctuations might occur. When in doubt, size up.
