1 LOT OF NEW IN BOX GENUINE HP 920XL BLACK (CD975AN) & MAGENTA (CD973AN) INK CARTRIDGES.. We purchased these ink cartridges for our own printer but no longer need these. Cartridges are still in factory sealed packaging and have never been opened or used and are the high capacity cartridges which means you are getting more ink for a lower price. In this lot you are getting a Black Cartridge and also a Magenta Cartridge. We believe that these ink cartridges are compatible with the following printers: HP Officejet 6500 Wireless - E709n (CB057A#B1H) ; HP Officejet 6500A - E710a (CN555A#B1H) ; HP Officejet 6500 - E709a (CB815A#B1H) ; HP Officejet 7500A Wide Format - E910a (C9309A#B1H) ; HP Officejet 6000 - E609a (CB051A#B1H).
