Ilford HP3 Photographic plates, 4x5". Your bid is for TWO boxes, ONE is sealed (12 plates) and ONE has been opened. I have weighed the boxes at 550g (sealed) and 180g (opened). I have NOT checked the contents of the opened box, clearly several have been removed. These are date expired vintage items offered as a collectors item, or for display/curiosity only. I have no idea how they have been stored, or the viability for actual use. They may be usable, but maybe not. There is just no way of knowing. I do not have a dark room and have not tried. Caveat emptor.
