To use these belts, simply wrap them around your waist and fasten the metal buckle. They're great for adding a stylish touch to your outfits. When it comes to maintenance, keep them away from water and excessive heat as this could damage the straw material. Since they contain chemicals like cadmium, lead, and nickel, avoid direct contact with your skin for long periods. Also, don't let children play with them unsupervised. Store them in a dry place when not in use to keep them in good condition.
