This discreet and convenient stainless steel accessory is a portable keychain with your Allen wrench close at hand. An ideal accessory for anyone who wants to "hold the key" to their Eternity collars, bracelet cuffs, or anklets.

  • Available to fit the classic (8mm) Eternity collars, cuffs, and chains. (1.5mm hex key).

Are you purchasing an older collar you already own?

Keep in mind these will not work with older Eternity Collars that use the 2mm screw(the screw hole goes completely through both sides of the collar and is visible on both sides of the collar) or the Thin Eternity Collars and Cuffs that use the 1.27mm screw.

Is there a way to get the Master Key as a necklace instead of a keychain? Yes. While the master key keychain isn't necessarily designed to be worn as a necklace pendant due to its weight, many of our customers combine it with one of our chain necklaces to wear and display as a pendant.

Make sure you read the fine print, this doesn’t work for the thin collars, cool product though, really hope they can make the 1.27 mm soon
