This 4Ocean beaded bracelet is super easy to use. Just adjust it to your wrist size (it can go from 7 to 13 inches or 18 to 33 cm). Since it's waterproof, you can wear it in the shower or at the beach without worry. When it comes to maintenance, just use a soft cloth to wipe it clean if it gets dirty. Keep it away from sharp objects to avoid scratching the beads and charms. And remember, by wearing this bracelet, you're also doing your part to clean up the oceans!
