Upcycled Carpenter Ruler Cuffs20th Century industrial debris as wearable art. Old (pre WWII) aluminum carpenters rulers are carefully cleaned, cut, forged and given new life as a fun and functional cuff. Cuffs measure 1 2" in width. Sizing is mostly for a medium sized wrist, but these cuffs are completely flexible just squeeze a bit or pull to shape as needed. They should fit even the biggest wrist with shaping, and should fit most smaller wrists easily with a quick squeeze.
