Look at these wonderfuly weird boxes (DiGiKerot himself calls them "obnoxious"). Since I almost never buy limited editions of anything, the only thing in my collection that comes close is the Stellvia tin.

Speaking of tins, small ammo boxes are an awkward fit. I'm thinking about trying the next size. Unfortunately, for the ease of transport, I have already standardized on the small box, so it's going to be a whole new set.
