We offer additional plastic seal locks, an option to pass checkpoints with a silicone cage.
These seal locks can also be used on any of the BON4M Series stainless steel cages.

Each seal shows a unique number. The different colors and prints allow variety.

Plastic seals have other uses than security gates. The unique number can be photographed when installed and at later intervals during your time in chastity to prove your obedience to your distant Keyholder.

Perhaps the most devilish use of plastic locks lies in the ease of escape. No hacksaw or bolt cutters needed. A house key, a kitchen knife and you’re free! But you’re busted! If you break out, you cannot conceal your misdeed from your Keyholder.

Order a set (10 pcs) to add a new dimension to your chastity games.

Subtle security: Individually numbered plastic locks

Soft and flexible, BON4 numbered plastic locks provide full security for your caged cock, while the release you crave so much is only a snip away. At any unobserved moment, or even with an illicit partner, you could reclaim your sexuality — but at an awful price. Though the security is easily breached, it’s impossible to do so without detection. Surely, such behavior would merit punishment and a long confinement if your Keyholder is even willing to continue the relationship!

Each lock is individually numbered, so your Keyholder can always check the number on your device. Make a note of the number and your security is complete. Away from home? Email your Keyholder a picture of your plastic lock in place with today’s headline in the background.

Use the specifications below to select a type. How you measure your Keyholder’s finger is left up to you.

Plastic locks coupled with a silicone chastity allow submissives to pass security checkpoints. Even x-ray screeners don’t present a problem. If questioned, take the moral high ground. “First, it’s none of your business. Second, I choose to wear decorative jewelry on my penis. Third, is it’s not a weapon and in its current condition couldn’t possibly harm anyone.”

In one sense, a plastic seal lock is more secure than even a BON4 metal lock. Such locks can be picked and replaced. Why not revel in the stark contrast between the soft vulnerable lock and the hard, implacable cage?
