Our recycling partners who produced the remanufactured C13T636800 used some of the highest quality dye based matte black ink when refilling these Epson units, the result being prints that can be proudly displayed. If held alongside pages produced by genuine Epson T6368 cartridges, the results will be comparable, but sadly do not offer the extended long-life protection of original matte black ink. This remanufactured Epson cartridge retains many components from the original C13T636800, but when necessary parts have been replaced with top-quality compatible parts. Our remanufactured Epson T6368 still offer compatibility with all the same incredible printers, and the keeps the 700ml capacity that you have come to love as well.
