Sculpted & carved in wax by hand & cast via lost wax casting. Cuff is adjustable, gently bend sides to tighten or lightly pull sides to open. Available in yellow bronze or sterling silver. *bronze can sometimes leave a faint green mark after being worn. This isn't true for everyone, but if you do encounter this, do not be alarmed. It's simply the copper content of the bronze alloy reacting with the acids of your skin. Simply wash wrists after wear.
