Black Onyx and Hematite Bead Bracelet Set with Chain Detail

Measure your wrist size
Use a normal tape measurer or a strip of paper just below the wrist bone, where you would normally wear a bracelet.

If you’re using a strip of paper, you can mark the overlap with a pen, and then measure the length with a normal ruler on a flat surface

See how this bracelet fits you. The average man's wrist is 18 cm.
