This paper is for making black-and-white prints from color negatives. It's no good for black and white negatives; I tried. Three of the 25-sheet packages are unopened. The fourth has been opened but seems to be near full. This paper was acquired in an estate sale and is of unknown vintage. However, I did test sheets from a fifth, opened package and there was no fogging so I presume the whole batch is usable. No warranty, however. Make me an offer: will trade for expired film (35mm or 120) or $25 cash.
