Simply Best !! 35

I have a Canon printer and bought the set, because my printer cartridges are simply too expensive.
The filling holes are clearly visible under the Etiket. I have the sticker then pierced with a gimlet and could refill the cartridges easily.

One should put kitchen towels under the cartridges but necessarily, because with me as the blue cartridge was not empty, so since the color is ran out down again!

While the printer still shows that the cartridges are almost empty, but it prints without complain (it only appears the window with the info about the low level).
