FREE: Kodak Polycontrast Acetate Filter 5" square PC 1-1/2, 2,3

The listing, Kodak Polycontrast Acetate Filter 5" square PC 1-1/2, 2,3 has ended.

Offering three vintage Kodak Polycontrast Acetate Filters. I am not the original owner and in fact know nothing about this item. There are three different codes on them as listed in the title. The seals on the back appear to be broken, but I have not opened them. I do not know if this effects the viability of the item, so they are being sold "as is". I have stored them in a cool dry place, but I do not know about how they were previously stored. Please feel free to email questions as my lack of knowledge about the item may have omitted an important detail.
