What is a martingale collar? A martingale is a collar that tightens when its chain is pulled and loosens as soon as the pull stops. It is also called limited-slip, because it only closes a set distance and no further. On the Halo Desire, two gold curb chains meet at an O-ring at the front. Pulling the ring draws the leather closer around the neck. Letting go releases it. In play, that gives the person holding the ring control over how snug the collar feels.
Halo Desire: a collar that tightens on a pull
The Halo Desire from Master Series is a black vegan leather collar with gold-tone hardware. The strap is 0.9 inches wide and adjusts to fit necks from 13 to 19 inches around. Two gold curb chains join at an O-ring that hangs at the front. When the ring is pulled the leather closes in, and when it is released the collar eases off again.
The chain unclips at a spring gate. Without it, the collar is a plain black choker that can be worn as an accessory. The rings are riveted onto tabs made to take a pull. The hardware is nickel-free and the materials are listed as phthalate-free.
Best for: For couples exploring dominance and submission who want a collar with a little more feedback than a fixed band. The distributor lists it under beginner bondage. It also works as a fashion choker with the chain removed.

How to use
Fasten the collar around the neck with the chain slack. Before anyone touches the chain, check that two fingers fit under the leather; a martingale closes from wherever you set it, so the starting fit matters. Clip the chain on at the spring gate if it is not attached. Pull the O-ring gently to feel how far the collar tightens, and agree on a signal to stop. Use short, light pulls only. Never attach the ring to a fixed point, never leave someone alone while it is clipped to anything, and never use it to bear weight.
Care
- Wipe the vegan leather with a damp cloth and dry it straight away.
- Polish the hardware with a soft, dry cloth.
- Keep it away from soaking, heat and harsh cleaners.
- Store it flat in a cool, dry place.
- Keep it out of direct sunlight.

Frequently asked questions
What neck sizes does it fit?
The collar adjusts from 13 to 19 inches in circumference. Measure around the middle of your neck with a soft tape and add room for two fingers. The strap itself is 0.9 inches wide.
How tight does it get when pulled?
A martingale only closes by the length of its chain loop, and it starts from the fit you set. If two fingers fit under the leather at rest, a pull makes it snug. Release the ring and it loosens again.
Can I wear it without the chain?
Yes. The chain unclips at a spring gate. With the chain off it is a plain black vegan leather choker. Clip the chain back on when you want the tightening function.
Is it real leather?
No. The strap is vegan leather. The metal parts are iron and zinc alloy with a gold-tone finish, listed as nickel-free. Clean it by wiping, not washing, and dry it right away.
Is it safe to attach a leash?
A leash or a finger through the O-ring is the intended use, with gentle tension only. Do not tie the ring to furniture or any fixed point, and never leave a collared person unattended while it is clipped to something.
