Whether it is to give your key fob to a mechanic, keep your pockets unencumbered on a long hike, or easily plug in a keychain USB, detaching pieces from a normal keyring can be a pain. That is, unless you have the Prometheus Lights Kappa Quick Release. Made in-house at their Mountain View, CA facility, you can remove necessary items with ease, thanks to the Kappa QR's simple push/pull functionality that is made secure by the custom-manufactured canted coil spring and solid construction. It comes in your choice of brass, copper, electroless nickel, or Delrin.
