Key Features Tightens On A Pull, Opens On Mercy: Two gold chains meet at the center ring. One tug closes the leather, and letting go hands your air back. Two Looks, One Collar: The chain unclips in a second, leaving a plain black unsuspecting choker that nobody would second guess. Gold On Black: Curb chain, rivets and rings in gold against vegan leather. Nickel-free and safe against sensitive skin types. Good Girl Certified: A beautiful accent piece for a night out that transitions with no adjustments the moment you bring the party to the bedroom. The Halo Desire O-Ring Collar looks like jewelry and behaves like a leash. Two gold curb chains meet at a spring-gate ring, so one pull draws the leather closed and letting go opens it again. Unclip the chain and you have a plain black choker for the hours when a gold ring at the throat would start conversations you would rather not have, or would you? Premium Nickel-free and phthalate-free, adjusts from 13 to 19 inches and fits most size necks. Put it on. Clip the chain. See who reaches for the ring first. Expert Tip: Two fingers under the leather before the chain goes anywhere, because a martingale tightens from wherever it started. A clipped collar is never one you leave somebody alone in.
