In this instructional video we show how to put on the BON4M (medium size) stainless‑steel male chastity cage onto a real penis. Attach the cage to your selected cock‑and‑ball ring, using the correct gap to ensure both security and comfort.

The BON4Mplus is a combo male chastity cage package that comes with 2 different sizes of stainless-steel cock cages. We’ve got multiple BON4Mplus combos in the shop—mixes and matches for every mood and every Keyholder’s whim. Dual-cage packs mean more teasing, more control, and way more options for both you and the one holding the key. This video walks you through a BON4Mplus set that includes the BON4M (medium) and BON4ML (large). Watch how easily your cock gets locked… and unlocked… while your Keyholder handles the swap—and your hygiene.

In this brief film, you’ll see the different chastity cage sizes—and all the back rings—on display.
