Using this deck box is a breeze. Just open the box by pressing the dual thumb notches. Then, you can easily put your double - sleeved trading cards inside. When you're done, close it, and the strong magnetic closure will keep it shut. As for maintenance, you can use a soft, dry cloth to gently wipe the leatherette finish if it gets dirty. Avoid exposing it to extreme heat or moisture as this could damage the leatherette and the magnetic closure. Also, don't overstuff the box beyond its 100 - card capacity to prevent any damage to the cards or the box itself.
