Nintendo Game Boy Advance Mega Man 4 e-Reader Cards offers Booster Box

Product Name: Nintendo Game Boy Advance Mega Man 4 e-Reader Cards offers Booster Box
Box is factory sealed and contains 30 sealed packs of cards. Each pack contains 5 cards, for a total of 150 cards. This is a Japanese imported product and will not work with an American e-Reader device or an American Mega Man Game Boy Advance game/system. Japanese hardware is required to scan these cards or offers you can just collect them (which is what I did).
