Using these denim headbands is easy. Just wrap them around your head and adjust for a comfortable fit. They can be worn casually for daily outings or dressed up for special events. When it comes to maintenance, spot - clean them with a mild detergent and cold water. Let them air dry. Remember, due to the warning about lead and cadmium, keep them away from children's mouths and avoid any actions that could release the chemicals, like chewing or breaking the headbands.
