There are three sizes of the bracelets:
Small (S): 6.5in/16,5cm
Medium (M): 7.25in/18,5cm
Large (L): 8in/20,5cm
How do I know which size is good for me?
First, you will need to measure your wrist. See pictures.
Then, to the size of your wrist add 1-1.5 inch for space, the sum will tell you which size you should order.
For example:
Wrist size: 6 inch
Add: 1 - 1.5 inch
Sum: 7 - 7.5 inches
RESULT
Medium (7.25 in) bracelet will fit you best!
