I have a black and a color ink cartridge, HP 338 / 343, new but no longer in the package. We bought them, popped them in the printer, and discovered they are not compatible with our printer despite the labelling.

They are free to the first taker willing to meet me to pick them up (Zurich Roemerhof tram stop or thereabouts). Alternatively, I could mail them for the price of the postage, although since we threw out the box I am not sure how well they would fare in the mail.

Send me a pm if you are interested.
