The KINK3D Airlock™ is a KINK3D original, metal-free lock adaptor. It 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. If you need additional numbered plastic seals, they can be purchased here.
Recommended for use only with Cobra chastity cages. The Airlock is not designed for use with KINK3D Shaft Rings, as the numbered seal would rest directly on the skin.
