Using this deck box is a breeze. First, open the box gently and place your double - sleeved cards in the extra thick inner sleeves one by one. You can also put in accessories like dice or small tokens. When closing the box, make sure it's properly sealed to keep your cards safe. For maintenance, wipe the box with a soft, dry cloth regularly to keep it clean. Avoid exposing it to extreme temperatures or direct sunlight, as this could damage the box and your cards. And always handle it with care to prevent any accidental drops or bumps.
