The BakuCase was a case for carrying Bakugan, originally presented at the 2010 World Toy Fair. It comes in all different colors, and always included a Helix Dragonoid. It had a holding device compatible with Bakugan Traps and Bakugan Battle Gear. But when sold in stores, the name was changed back to BakuBox.
Each BakuCase can hold 28 Bakugan spheres. You can put two BakuCases back to back and combine them to form one larger case.
