Packs are Brand New Factory Sealed, each cardboard blister has been opened at the bottom and Secret Foil card turned to face forward. I didn't realize this until after I purchased from the store. So you can see what hidden card is in each blister. I've also included side pictures so maybe you can tell which monster pack in inside based on color of packs. Selling off all my YuGiOh collection, feel free to email me if you're interested in multiple items or want to purchase all.
