Notes:
1. A bracelet is perfectly sized when you measure your wrist tightly and add 2 or 3 cm.
2. If you are between sizes, ask yourself how you like to wear your bracelet. If you wear it tightly choose the smaller size and if you like to wear it loosely take the next size up.
3. Please be aware that when you receive a new bracelet it will feel stiff, which can make it uncomfortably tight. The bracelet will quickly soften and become more flexible as you wear it.
4. Bear in mind that the more charms you add to your bracelets, the tighter it will become.
