This bracelet is super easy to use. Just adjust it to fit your wrist comfortably. Since it's waterproof, you can wear it while swimming or washing your hands. But to keep it in great shape, avoid harsh chemicals like bleach. When you're not wearing it, store it in a dry place. If it gets dirty, you can gently clean it with a soft cloth and mild soap. That's all you need to do to enjoy this eco - friendly bracelet for a long time.
