These cartridges I very quickly get ..I was also here ... very surprised at this rapid and very fast delivery .. Thanks for that ... although they fit into my Canon printers .... I know now ..but I unpack me when installing and handling the cyan cartridge I desperately needed ... and when inserting the cartridge. .so very dirty with this color on my two hands and fingers ..what has never occurred in a cartridge change .. maybe an operator error or clumsiness of my side :: Unfortunately, I no longer put that color cyan time being of my finger off. .all is blue ..leider .. I just hope that the next cartridge change works better and my hands stay clean ... otherwise there is really nothing to complain about ... everything else seems to be so far ok! Thank you Lg Schmitt Armin
