Our bracelets are water resistant if they don't have any metal charms on them. Due to the plating of these charms, they will eventually fade over time with normal wear from water, sweat, perfumes and other substances. Stretch cords will naturally lose its stretchiness over time and your bracelet will eventually need to be restrung. The best way to put on your stretch bracelet and prolong its lifetime, roll the bracelet on your wrist and avoid stretching the cord too wide.
