Selling: 1 - unused, unopened, Black ink, 82 / #82 (18L0032/18L0234), ink-cartridge, 600 pages; 1 - unused, unopened, Color ink, 83 / #83, (18L0042) ink-cartridge. Compatible Lexmark printers: X5100 Series, X6100 Series, Z55 Series, Z65 Series. Note that the cartridges are "new", but also are "old stock", since there is no support for my (now-end-of-life-and-responsibly-disposed) printer within Windows 10. Original price was $42/cartridge. Now offered at $40 for the pair.
