This cock ring is simple and easy to use. Perfect for beginners starting out, there’s no worry about abrasive metal, sizing, or getting a size that’s too small. The leather strap wraps around the base of the cock and has a velcro closure. To use, simply use a little lube at the base of the shaft, allow yourself to get erect and then wrap it around the base of the shaft above or below the balls. Find what fits best for you. Over time, the leather will stretch slightly if needed for a custom fit. If it ever gets uncomfortable, simply pull the strap to pull the velcro apart and release. To clean the leather, use a damp cloth and mild soap and water to spot clean or wipe down the straps. You can also use a toy cleaner to wipe the straps clean. Then use a leather conditioner when needed to keep the leather nice and soft for long-term use.
