This is the 5 pack multipack with pigment black, black, cyan, magenta and yellow. Then there is a 4-pack without the pigment black, but with black, cyan, magenta and yellow: Canon CLI-571 Multipack (Multicolour, Original Product) These are the only two multipacks in this series. All colours are of course also offered individually. Unfortunately, grey is not available in a multipack, so this colour can only be purchased individually.
