The Folsom Knife - Black + Black
Solid brass key ring by Brooklyn, NY based Maxx & Unicorn. These minimalistic key chains are made of solid brass with a threaded hex-shaped closure and laser engraving. Easily holds more than a dozen keys, yet keeps them compactly folded within the key ring.
Matte Black Oxide (MBO) is a semi-permanent finish used to coat solid brass. It is designed to wear, chip and fade over time, exposing the solid brass base beneath.
