Bakugan ROCK HAMMER Tan Silver Battle Gear Gundalian Invaders 60G DNA. No cards are included. It has been tested to make sure it opens and closes properly. Stubborn to open. I don't play this game and they have been checked for authenticity by researching numerous sites on the internet dedicated to Bakugan. I have more Bakugan listed and some seem a bit stubborn to close. The pics were taken weeks ago and so I'll test again prior to packing and shipping. Questions and sharing additional info about these is welcome Please view pics for the visual description. From a smoke free environment. Thanks for looking.
