HAS TO BE SURGICALLY REMOVED. DO NOT BUY!!!!!!!!!!! review by Fred on 4/25/2016
Because of a plug very similar to this one I was sent to the emergency room. After the meatus passes the widest part of the plug it becomes trapped by the squares edge of the plug. It should taper on both ends of the sound. The square edge acts like a barb and cannot be removed from the penis causing minor surgery to remove it.
