The CB-6000 Small is the manufacturers way of adding another design to provide personal choices for all types of male anatomy. Polycarbonate material is used due to its light weight and durability. The cage portion has the vented slots for hygiene and also allows for natural air drying. The bottom opening allows for use at the urinals. You may want to have a piece of tissue handy to wipe any drips. Make sure to wear a numbered plastic lock if going through any metal detectors. It has been reported that some men have worn the brass padlock and have not had any alarming experiences, however, the plastic lock is still recommended. We highly recommend using a silicone based lubricant after showering. This allows the penis to naturally move up and down in the cage portion. After a break in time period you should be able to wear it for 24/7 for an indefinite period of time. Wearer and Keyholder ultimately determine the length of time. Each Order includes the following: 1.One Cage Portion 2.Five different sized rings 3.Four locking pins 4.Four spacers 5.One brass padlock with ONE key 6.Five individually numbered plastic locks 7. An embossed zipper pouch. NOTE: Some men have a high/tight ball sac. If this is the case it may take a little longer to get a comfortable exact fit. For the best results the ball sac should hang slightly below the ring and the cage portion. You may find it necessary to wear a 1” leather strap with snaps at the top of the ball sac off and on for a while until it stretches slightly. Most adult stores carry this product.
