This ink formula is specially designed to produce vibrant and long-lasting prints comparable to HP. After carefully inspecting the shell for leakage and monitoring the electrical circuitry for efficiency, we put the cartridge through a final print test to be certain it is worth of our 100% money-back guarantee.
