The KINK3D Airlock® is one of our original creations! It’s a 3D-printed lock adaptor, which can be used in place of the standard lock when you need a 100% metal-free setup.

The plastic seal with a unique number can also be used to prove how long you’ve been locked.

Each Airlock comes with 10 numbered plastic seals included.

The Airlock is recommended for use only with Cobra chastity cages.
