Designed for long-term wear, the Penis Chastity Fences attach via a secure padlock so there's no getting away. Suitable for long-term use, the body-friendly stainless steel design won't rust or tarnish, and have air vents for easy cleaning. The open-ended design allow you to urinate discreetly even at a urinal with the device in place. Our small cage measures 9cm (3.5 inches) and the large measures 13cm (5.1 inches). Take this into consideration if you are well endowed.
