BON4 Silicone Male Chastity Device - Regular

The BON4 silicone male chastity devices are the perfect introduction to chastity. The flexible light silicone material allows you to keep it on with your normal activities, and while wearing the BON4 it will be relatively difficult to notice under trousers.

Ideal on airports or at any security gate once the wearer of the silicone BON4 is locked up with the individually numbered plastic seal locks (provided with initial purchase). For those who have a larger penis, the BON4L could be a more suitable option.

Customer Reviews



Cannot recommend this enough. I have been thinking about doing chastity for a long time and finally got a partner who was into it. It is really great to wear long term once you get the feel for it (I even wore it on an international flight).
A few things I think any buyer should know:
1) it is difficult to exactly figure out how to put it on, but it's like riding a bike, once you get it, you never forget.
2) you can still jerk off using it, sounds like more of a problem than it is, my partner and I have found this more of a benefit honestly but just in case you thought it would stop even the most crafty person from getting off
3) always go for the 2nd smallest or smallest ring that you can get on, it's much more enjoyable when it's tight, and believe me after some trial and error.

Otherwise, have fun!
