Using this deck box is a breeze. First, open the box gently. Then, carefully place your double - sleeved cards in the extra thick inner sleeves one by one. You can also put your game accessories like dice or tokens in the available space. When it comes to cleaning, just use a dry cloth to wipe the box. Avoid using sharp objects that might scratch it. Keep it in a dry place away from direct sunlight to prevent color fading. Don't overfill the box as it may damage the structure and make it hard to close properly.
