A thrilling package that contains the steel cages of the BON4M as well as the BON4ML (Large). Both BON4M Series are the innovative models launched December 2018.

To make sure it all fits well there's also 9 different sizes of hinged CBR’s (rings). Take your time to find out which of the ring and cage sizes fit you best. The innovative CBR’s can be opened 360 degrees and are thus easy to put on as well as a pleasure to wear.

Once secured you can hand over the keys to your keyholder to stay obedient yet aroused. Your keyholder will from now be in total control of your dick.

Be prepared for a longterm sexual denial as well as erotic teasing. No more erections or cumming until your keyholder decides to release you.

To create an even better fit as well as security, the innovative BON4M Series comes with 3 different gap options (space between the cage and the selected ring).
