The security and design of the new BON4M Series raised the bar to a whole new level.
Measuring or worries about the right ring size is history as any of the BON4M's are delivered in a discreet package which contains next to the cock cage a wide variety of ring sizes.

On many persons request our great PROMO "purchase any BON4Msmall, BON4M or BON4Mplus and receive for free a BON4 silicone chastity device" will be valid again from June 22 until August 4 / 2018 - An ideal and wonderful combination!
 
Whether you are into forced, short or long term chastity,
our well designed cages will keep you controlled and locked for as long as your key holder decides to do so.
The very secure BON4M Series is ideal to wear for weeks or even months.
When finally released, the perpetual teasing and long periods of erotic sexual denial may lead to what many describe as the most intense and sensational climax.
Others may experience greater pleasure while staying locked and submissive, for as long as possible...
Chastity play can be such a pleasure, yet keep in mind that it still takes a good fitting device.
Very welcome and needed is thus the large selection of ring sizes (standard with any BON4M) that enables the wearer to create the right fit.
The look and the feel of the cold steel may attract many and once in practice, hygiene and ventilation should be no issue due to the many cage openings.
It might not take long before you consider our stainless steel design as your most precious possession.

As shown in our user friendly instruction movie, putting on any of the BON4M's is quite easy.
To ensure our customers the right fit all the cages come standard with a variety of  4 (solid) or even 7 (hinged) ring sizes.
Put your scrotum followed by your penis through the ring that fits you best.
Put the cage over your flaccid penis and secure the device with the small brass padlock.
Now you are caged in steel and there will be no more cumming.
Enjoy being submissive and spice up your relation with erotic play and kinky orgasm control.

Sizing is easy:
We advise those with a small / medium sized penis to select the BON4Msmall.
The BON4M has a relative large cage and is therefore ideal for men with a longer penis.
In case you would like to owe both cage sizes select the BON4Mplus, an ideal and complete Chastity Package.

Whilst checking out in our shop choose between Hinged or Solid back rings:
Opt for the solid version and you'll receive a cage + 4 sizes of closed rings (1.57″ 1.73″, 1.89″ and 2.05″)
Or the hinged version and you'll receive a cage + 7 sizes of hinged rings (1.57″, 1.65″, 1.73″, 1.81″, 1.89″, 1.97″ and 2.05″)
The hinged rings can be opened and are therefore easy to put on.
Take your time to try and find out which of the 7 ring sizes fits you best.
A very important detail, as once you secure the chastity cage to a ring that sits good, you'll have excellent comfort and security.
The solid version (closed rings) are to some a bit more difficult to put on (use some lub or olive oil) but on the other hand causes less or no pinching.

For the fellas that are really well endowed we created the 2.2" (56mm) ring. 
With the optional 1.4″ (36 mm) ring we kept in our mind men with a small scrotum but also those with only one testicle.
Both extraordinary ring sizes are fully compatible with any of the steel cages.
You can purchase these separately or simply add to your order whilst checking out in our shop.

The New BON4M series come with 5 unique laser engraved numbers on the stainless steel cage.
That way we can track your device and guarantee a genuine BON4M.
Beware: the popular BON4M has been copied and knock offs are being offered online!
 

All the BON4 products come with an attached tag.
