Handcrafted adjustable cuff bracelet featuring human anatomy, spine, pattern that was etched into copper. After etching copper cuff was hand sawed out, hand formed, oxidized to enhance details of the design then sanded back to a matte finish. Cuff is sealed to prevent a quick tarnish time though through wear and exposure to other elements (air, water, heat soaps etc.) it will tarnish in time. Though I do file, sand and polish this cuff please be aware that this cuff has edges that may get caught on/snag especially on loose clothing; it is also best to open up the cuff to slide on then squeeze to wrist.
