The Elegant Punk line utilizes 95-100% recycled materials. This cuff is fabricated from textured and patinated roofing copper recovered from a construction project, which envelops thick, lightweight aluminum grid from a local sculptor's spaceship fabrication project. Beauty from refuse, and completely one of a kind. This cuff is the last one in the line of this size (about 2 1/4" wide). Further cuffs will be smaller in size as the pieces left are smaller in size.
