The idea of such a box release isn't bad at all. This is something I been writing for years because I don't like the idea they mix different set packs in these promo boxes while each individual set is harder to finish because there are other set packs included and nowadays sets get bigger and bigger. That is especially annoying for those consumers who do finish their set and try to move on because then these extra unwanted packs are like rocks tried to their legs. That why I like special set releases because all the products include that set packs only and really don't take the mood away when trying to finish the set. Also, it is a perfect way to get rid of the extra printed stock because if it is done right and proper cards are placed then collectors who haven't finished the set can be attracted, like me.
That been said. why on earth Pokemon company didn't put in 2x EX Full art cards of these prints instead to lure consumers. Personally, from these 2 boxes, I am only missing Mewtwo EX and rest I have it, meanwhile from full arts I'm missing Mega Charizard EX full art, Dragonite, Mewtwo, and Pidgeot which really would have given me a reason to buy these to finish the set. And the Jumbo cards are a nightmare to protect since there are no dedicated high-quality perfect fit sleeves for these, I would have rather prefer a figurine or pins.
Overall I think I would rate this product 5/10 but clearly there is much to do to improve. I might buy these during Black Friday sales if there is a discount on these products.
