Our exciting combination, the BON4Micro, the BON4M and the BON4ML, does more than ensure nearly all men will find the properly fitting cage.

You may be fortunate and fit in either cage, so your Keyholder determines your degree of confinement.

Watch our brief demonstration video before your first fitting.

Once you’re safely caged, present yourself and the key to your Keyholder as a supreme act of submission.

Congratulations!
You’re now at your Keyholder’s mercy.
How long until you gain release?
No telling.
We suggest you remain docile and obedient at all times.
That’s your best hope for gaining release.

Features of this versatile option include:

Three cages ensure proper fit, whether attempting to grow or fully relaxed.

Possible option of greater or lesser restriction at your Keyholder’s whim.

Either cage makes an attractive package of your package.

Five sizes of spacers and locking pins allow you choose the correct ring-to-cage distance.

7 diameters of cock and ball rings at 2 mm increments keep you secure as well as comfortable.

All rings swivel 360° for easy placement.
