This is the "Gekitou! Bakutech Colosseum Bakugan Official Battle Field W Super DX Set" that has been stored at home. There are 12 Bakugan. (One of them, a dark red one, would not open.) Some items may be missing from the original set. All cards I have at home will be included. Please check the images. There are also unopened parts. I don't remember assembling the battle field, but there are dents on the surface from storage. As this is a used item, please understand that there may be dirt and damage. (The box also has damage from storage.) I plan to wrap the box for shipping. (The Bakugan will be wrapped in bubble wrap, and the cards will be placed in OPP bags and packed inside the box.)
