Using this belt is super easy. Just thread it through the belt loops of your dress shirt. You can adjust it to your desired tightness with the pin buckle. When wearing it, you can also loop the shoulder strap over your shoulder for a more fashionable look. As for maintenance, keep it away from sharp objects to avoid scratches. If it gets dirty, you can use a soft, damp cloth to gently wipe it clean. Store it in a cool, dry place when not in use to maintain its quality.
