This box is a replacement for the cardboard insert that used to come in Magic bundle boxes\fat packs. I always wished they came with 2 so I decided to make my own. They are the perfect size to hold a commander deck, and a bundle box holds 2 with a bit of extra space for some tokens or extra cards. I also created a lid so if you are anything like me and have decks and piles of cards everywhere you can keep your cards dust free. I would not use the cover as a deck box as it is a touch loose for that purpose. I really just made it so I could stack cards on the shelf and keep the dust off of them. you can print 4 inserts at once on an a1 mini and 9 on a p1/x1/a1.
