Using this belt is easy. Simply insert the belt through the belt loops of your pants and buckle it up. When choosing the size, always refer to the size chart provided to ensure a perfect fit. As for maintenance, keep it away from sharp objects to avoid scratches on the leather. If it gets dirty, you can gently wipe it with a soft, damp cloth. Don't expose it to direct sunlight for long periods as this may cause the color of the leather to fade. Store it in a cool, dry place when not in use to keep it in good condition.
