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 natural 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. 

Sizing is quite easy as the penis cages come in 2 sizes:
Those with a small or medium sized penis select the BON4 and those with a large penis select the BON4L.
Or combine both cage sizes in 1 complete chastity package and select the BON4plus.

The ergonomic design of this chastity device allows the wearer to keep it on while showering or during a visit to the men's 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 key holder decides to do so.
