How to use: Just put on the bracelet and adjust it to your desired fit between 7 - 13 inches. It's waterproof, so you can wear it while swimming or in the rain. Note: Although it's durable, avoid excessive pulling on the bracelet. Maintenance: You can simply rinse it with water if it gets dirty. Keep it away from sharp objects to prevent scratches on the stainless - steel charms and glass beads.
