Bento box boobs from the local convenience store. The cashier girls breasts are by the stores policy, open for purchase for an obscene sum just to drum up business thru word of mouth, not really to actually be sold, while cold cut woman meat bits and so on are available for a much cheaper sum at the store. Unfortunately some of Maries's class mates found out her boobs were up for sale and used a large sum of cash they all got together for the boob sushi bento box to her chagrin.
