8 1/2 inch Round Double Loop Bangle Bracelet with a St. Patrick charm. To ensure that your bracelet fits as close to ideal as possible, please measure your wrist with a tape measurer. If you do not have one, you can use a piece of string to wrap around your wrist and then measure the string with a ruler. Once you have your wrist size, add at least a ½ inch for the proper bracelet size.
