Two multi-cartridge boxes are Inkredible replacement cartridges for Canon CLI-570 (Black) and 571 (Colours). These came from a Pixma MG5750 but fit some others. 9 cartridges in all.
Had no problem with Inkredible replacement cartridges and, unusually for replacement ink suppliers they accept empty Inkredible cartridges for recycling. But maybe easier to use local Curry's which I think accepts used cartridges for recycling.
