My Pixma Inkjet printer is irretrievably broken. Have replaced it, and so no longer need the cartridges I had as back up. I have 1x a 551XL BK, and 1x a 550XL PGBK, unopened original Canon ink cartridges. Also happy to throw in the cartridges that are currently in the old printer... these will be 551XL in black, grey, cyan, yellow and magenta and 550XL in black... of these, from memory, 2, I think the cyan and magenta, were swapped in recently, and probably have a lot of ink left. No idea what the state the others are in.
