These professionally remanufactured cartridges are original 18C1523 #23 inkjet cartridges which have been through one cycle of service and have been recharged. Each cartridge has been thoroughly cleaned and inspected for any possible shell leakage, tested on the operation of all electrical circuitry, and run through an actual print test. Our remanufactured cartridges are also backed by a two-year warranty and guaranteed to meet or exceed the same quality standards as the original OEM brand. Please note, retail packaging may vary and these items will only work with printers purchased within the United States and Canada.
