The bypass bracelets do not slide straight on over the hand. Instead, hold the bracelet’s opening parallel with the length of your arm/wrist, sliding your wrist in, and then turning the bracelet onto your arm. It seems complicated at first, but will soon become second nature – don’t worry! If need be, you can spread the opening wider to more easily accommodate your wrist. If you are having problems with the sizing after you receive the item, contact us and we will help.
