Can anybody tell me where white cardboard specimen trays/boxes can be
obtained?  I am thinking about the small and medium sized ones that
museums and institutes use to put specimens in (the ones that organize
nicely in drawers because the sizes increase so that the width of the
next larger size is equal to the length of the smaller one etc...).
I suppose I could make my own from white cardboard but if they are
available and not too expensive I'd sure like to get some.  Part of my
collection is already in such trays but I can no longer get more from
that source.
