Using your 4Ocean 4 Fish Macrame Bracelet is super easy. Just adjust it to fit your wrist as it can be set from 7 to 13 inches (18 to 33 cm).

Just wash it with mild soap and water occasionally. Keep it away from sharp objects to avoid tearing the cord. And remember, by wearing this bracelet, you're supporting the use of recycled materials.
