I have this problem, why i can't buy those 3-boxes from those well known online stores? My problem is that i shoot more than one kind of film [B&W and colors] and i don't have any empty box yet and i can't find it anywhere here in my country, and asking some members here to sent it to me will cost me more than just box of sheets pack, but i wish to find those boxes for storage from some online dealers/stores.
