Using this deck box is a breeze. Just open the lid and gently place your double - sleeved cards in extra thick inner sleeves inside, along with any accessories. When closing the box, make sure it's properly sealed to keep your cards safe. For cleaning, use a soft, dry cloth to wipe the exterior. Avoid using harsh chemicals as they may damage the box. Store it in a cool, dry place away from direct sunlight to prevent color fading. If you're transporting it, try to keep it upright to avoid any potential damage to the cards inside.
