Temporary promo: We'll add a free BON4 male silicone chastity device with every purchase of the hinged BON4M Series.

The BON4M Series in stainless steel to stay submissive and devoted to your Keyholder. No more measuring, or worries about the correct ring size(s), as all of our cages come with a large selection of cock and ball rings. We are very pleased with the launch of these innovative high-quality male chastity packages.
The recently launched new designs are being offered in 4 different sizes of stainless steel cages. The BON4Micro is basically ideal for men with a quite small flaccid penis. Very nice too for those who are into little dick humiliation. Do you, or your partner, consider the length of your flaccid dick somewhere in between 2.6″ and 4″ then you should go for the BON4M.
Those blessed with a large dick we strongly advise to select the new BON4MLarge and our latest chastity device, the BON4MXL, is for the really big boys.

On this website, you’ll find plenty of detailed product information such as instruction movies in which is shown how to put the device on. We have also created lots of 360’s in which you can view any detail from any angle.
