Very effective, can be worn under loose fitting clothes. Made from high quality 5-7 oz. black latigo. Designed with comfort in mind, this high quality restraint can be worn for long periods of time. All hardware is constructed out of stainless steel or nickel-plated brass. Very practical, unlike the "cage" versions out there, this restraint allows for normal daily activity (since the head of the penis is not obstructed you can safely and cleanly use the restroom) while discouraging penile shaft enlargement, all at a price well below any other male chastity devise on the market. Overall length is 3". Locks and keys included.
