Ilford FP4 Photographic plates, 4x5". Your bid is for ONE opened box. I have weighed the boxes at 1.3kg. I have NOT opened the boxes to check the contents. 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.
