The Damascus Glow Lume Cuff, Two Sizes by Chris Ploof are each a heavy gauge Damascus Steel hand crafted cuff bracelets. Each cuff shows off Ploof's impressive signature swirl pattern and a light oxidization for a stark contrast. The swirl is then painted with a special Lume UV activated glow-in-the-dark enamel. Each cuff comes with it's own small UV keychain light.
