Bon 4

BON4 Transparent Penis Cages will fit as good as anyone because these come with 4 different sizes of silicone back-rings.
The design and light high-grade silicone material are more or less based on a wearer who appreciates a more comfortable device.
The flexible light silicone material allows you to keep the device on during your normal activities, and while wearing the BON4 it will be relatively difficult to notice under trousers.
The naturally shaped penis tube can be securely locked with our standard 15mm brass lock or with one of the individually numbered plastic seal locks. Feel comfortable while traveling or while passing a security gate.

The ergonomic design of this chastity device allows the wearer to keep it on while showering or during a visit to the mens room.
The BON4 Silicone is relatively easy to put on, feel free to take a look at the instruction movie on this web page.

Whether you are into orgasm control, forced or long term chastity, your penis will stay locked for as long as your Keyholder decides to do so.
