HOW TO MEASURE
STEP 1: Measure your wrist with a flexible tape measurements or a strip of paper just below the wrist bone, where you would normally wear the bracelet.
STEP 2: If you are using a plain strip of paper, mark your size with a pen or pencil then use a ruler to measure the length, and give your wrist a loose fit to move around.
