Using these belts is super easy. Just wrap them around your waist and fasten the pearl metal buckle. When wearing, make sure the buckle is properly closed to avoid it coming undone. For maintenance, keep them away from sharp objects to prevent scratches on the buckle. If they get dirty, you can use a soft cloth to gently wipe them. Remember, due to the warning about chemicals, avoid long - term direct skin contact and always store them in a dry place.
