Think of it as a journal for your wrist, or a low-tech Fit Bit. Slide the beads from one side to the other as you work toward a goal. The beads stay put until you move them again. Track pounds lost, daily glasses of water, acts of kindness, or anything you want to accomplish. Copper cuff is dipped in .925 sterling silver. About ¼" wide, 2¾" diameter (standard size), slightly adjustable with a gentle squeeze.
