These are booster boxes for the Meta X Justice League card game. These boxes look different, but Panini has made several releases for Meta X using these black and white boxes rather than the conventional box art of other card games. These were also bought from a distributor so perhaps the kind of product depends on what channel you get it through.

Nevertheless, these boxes contain 24 packs with there being 12 cards per pack. Boxes are in great shape and are sealed.
