Using this card holder is a breeze. Just open the kiss clasp and slide your cards into the accordion - style compartments. To keep your cards safe, always ensure the clasp is properly closed. When it comes to maintenance, use a soft, dry cloth to gently wipe the surface of the holder. Avoid exposing it to harsh chemicals or excessive moisture, as this could damage the synthetic brocade fabric. Also, don't overstuff the holder beyond its 10 - card capacity to maintain its shape and functionality.
