Old paper stock. It's definitely fogged, but I believe that's okay if you do lumen prints. Feel free to correct me, I've never actually done lumen prints. :confused:
I have a 250 sheet box of letter size Kodak Polycontrast RC II which expired in 2005. It's been opened but it's almost totally full. Weighs a ton. Kind of hurt my back picking it up!
Also have 70 or so sheets of 8x10 AGFA MCP RC which has no date but looks about 2005ish as well.
$40 for the paper, plus shipping, OBO. I could pack it and send it book rate/media mail. Would take a week or so but they really give you a good price. Probably around $10.
