FS: Slide mailers, slide archive sleeves

I'm cleaning out some stuff and found things I should get rid of:

Print File archival slide sleeves, style 2x2-20HB. Probably at least 30 of them brand new, still in plastic bag. Plus quite a few extra used ones.

5 Kodak PK20/24 prepaid mailers (20/24 exposure roll of 110, 126, or 135-size Kodachrome, Ektachrome, or other E6). They are addressed to Fair Lawn, and I think that plant closed, no? No idea if someone can use these, either for mailing slides to another Kodak plant, or if just for posterity/collecting.
