Using this deck box is a piece of cake. First, open the box by releasing the click - lock mechanism. Then, place your double - sleeved cards in thick inner sleeves inside. You can stack them neatly. When you want to check the top or Commander card, just look through the translucent part without opening it. When playing your trading card game, you can split the two symmetrical parts of the box to use one as a card pile holder and the other as a discard pile holder. As for maintenance, keep it away from sharp objects to avoid scratches on the translucent area. Wipe it with a soft, dry cloth if it gets dirty. Don't expose it to extreme heat or cold, as this might damage the click - lock mechanism and the overall structure of the box.
