Using the Bastion 100+ XL Clear is a breeze. First, open the box by gently releasing the click - lock mechanism. Place your double - sleeved cards, with Thick Inner Sleeves, inside the box. You can neatly stack them up. When you want to view the top or Commander card, just take a look through the translucent part without having to open the box. To use it as a card pile and discard pile holder, simply re - arrange the two symmetrical parts. As for maintenance, keep it away from sharp objects to avoid scratches on the translucent surface. Clean it with a soft, dry cloth regularly. Also, don't expose it to extreme temperatures, as this might affect the click - lock mechanism and the overall structure of the box.
