Using this deck box is super easy. Just open the box by gently pulling against the magnets, and you can quickly access your double - sleeved cards. To customize, feel free to remove the lid and attach it to the bottom or tilt the box as you like. When closing, make sure the magnets align properly for a secure fit. As for maintenance, keep it away from sharp objects to avoid scratching the Nexofyber surface. You can use a soft cloth to wipe the inner microfiber lining if it gets dirty. Also, store it in a dry place to prevent any damage to the cards and the box itself.
