BON4 Stainless Steel Chastity Device - Regular


* Required Fields

New design!

The BON4 Metal Chastity Device is the ideal cage for small & medium sized flaccid penises between 3″ and 4.2″. The third generation BON4M comes with a new and easier locking system and offers the wearer 3 different gap options.

Secure the cage to the chosen cock and ball ring size and select the best gap for your security as well as your comfort.

The new CBR’s (cock and ball rings) cause no or very little pinching and are therefore only available in the improved hinged version.All BON4M’s come with standard 7 different sizes of hinged cock and ball backrings; (1.57″, 1.65″, 1.73″, 1.81″, 1.89″, 1.97″ and 2.05″).

Once you lock the high quality cage to the best fitting ring you’ll be perfectly secure. The ergonomic design of the innovative BON4M allows you to wear this serious device 24/7. From the moment you are locked inside the cage there will be no more erections, masturbating or cumming. Stay submissive and be controlled for as long as your Keyholder decides to keep you locked up.

Once released from the erotic teasing and orgasm denial, you'll enjoy an unforgettably intense climax. Or you could stay locked down and controlled for long periods to enhance the pleasure of chastity play.

Customer Reviews

Best cage.


I ordered this cage on a Saturday morning and received it on Wednesday. Have been wearing it since I opened it up and absolutely love it. I can't see myself taking it off anytime soon. It is very comfortable to wear. Would 100% recommend it to anyone looking for a cage.

Looks good and feels great.


A great chastity cage. Its well made, loads of cock rings for sizing (which is great as I will wear a smaller ring than my usual fixed metal ring due to the easy opening hinge). The cage has some weight which pulls the ring forward. The weight also feels great. The cage is comfortable and smooth so no issue getting a semi and restricted/pushing on the cage..
