Product Highlights:

• Tightens On A Pull, Opens On A Whim: Two gold curb chains meet at the ring. Pull it and the leather closes. Ease off and you get your air back.
• Two Collars For The Price Of One: The chain unclips at a spring gate. Without it you have a plain black choker for the day. With it and you have a collar that closes when somebody pulls.
• Fits Most Neck Sizes: 13 to 19 inches on a 0.9 inch strap, with the rings riveted onto tabs built to take a pull. No pinching, no gaping, no crying.
• Body Safe Materials: Nickel and phthalate-free hardware that's safe on sensitive skin. Wear it for hours without any irritation or concerns.

A martingale is the design that tightens when the chain is pulled and loosens the second it's let go. Dog people call it limited-slip. In a bedroom it means one person decides how much room the other one gets.

Black vegan leather, two gold curb chains, a spring-gate ring hanging at the front. Take the chain off and it's a choker. Put it back on and it very much is not.

Fit it. Clip it. Hand the ring over.

Expert Tip: Get two fingers under the leather before anybody touches the chain, since a martingale closes from wherever you set it and not from zero. A collar clipped to something is never a collar you walk away from.
