To use this belt, simply slide it through the belt loops of your pants and fasten the buckle. Make sure to adjust it to your desired tightness. When it comes to maintenance, use a soft, dry cloth to wipe off any dirt or dust regularly. Avoid exposing it to excessive moisture or harsh chemicals, as this may damage the PU or alloy. If you're not using the belt for a long time, store it in a cool, dry place.
