The BakuBoxes are smaller versions of BakuCases. They can hold a maximum of 24 Bakugan; if Gate Cards and Ability Cards are placed in the middle, it holds 18 Bakugan total. They come in translucent blue, red, and white. Each season has a different design: Battle Brawlers is a basic rectangle, Gundalian Invaders has a more complicated interlocking pattern, and Mechtanium Surge features a design with a larger upper section.
