Buying ink in a multipack is a great way to save money. This is the Canon PG-40 and CL-41 multipack that contains one PG40 black cartridge and one CL41 colour ink cartridge. The colour cartridge in this pack is a C, M, Y which means it contains Cyan, Magenta and Yellow ink in the same unit. In this combo you get 16 ml of black and 12 ml (total) colour ink that will produce crisp prints that are smudge resistant and professional in appearance. Individual versions of these cartridges are also available.
