Sophia Global Remanufactured Ink Cartridge Replacement for Dell J5566 and J5567 (2 Black, 1 Color) These cartridges were professionally remanufactured in an ISO 9002 factory. Each cartridge was used once and then sent to our factory where it underwent an extensive process including, cleaning, testing the chip, and ink refilling. Before being sealed, each cartridge is tested in a live printer to ensure crisp text and true color reproduction. The cartridges are finally sealed, and placed in a static protective bag.
