Using this backpack is easy. Just open the main compartment and start filling it with your loose sleeved TCG cards. You can neatly stack them up to make the most of the space. For your MTG playmats, use the exterior pockets and secure them with the playmat straps. When you're done with your game, make sure to close the backpack properly to keep your cards safe. As for maintenance, wipe it down with a soft, dry cloth if it gets dirty. Avoid getting it wet or exposing it to extreme heat. That way, your backpack will stay in great shape for many gaming adventures.
