The community sounds perfectly friendly except for the kerfuffle - as far as I could tell, caused by someone objecting to a woman who both participated in the comm and promoted a friend's bento-box-importing business in order to practice her online-marketing skills (does online marketing advice for a living).

Even if I don't find a set, assembling one out of all the kinds of boxes on offer shouldn't be hard :) The very same kerfuffle-cause suggested getting novelty-candy containers for dressings, which I think is worth a try :)
