Using the Extra-Large Bastion 100+ deck box is a breeze. First, open the box using the click - lock mechanism. Then, carefully place your double - sleeved cards in thick inner sleeves inside the box. You can stack them neatly and keep the top or Commander card visible through the translucent part. When you're playing your trading card game, you can convert the two symmetrical parts into a card pile and discard pile holder as needed. As for maintenance, keep the box away from sharp objects to avoid scratches. If it gets dirty, you can use a soft, dry cloth to wipe it clean. Don't expose it to extreme temperatures or humidity, as this might damage the materials. That's all you need to know to get the most out of your deck box!
