This multipack contains one each of the original Epson 603 ink cartridge range, giving you black, cyan, magenta and yellow in a single box.Compared to the high capacity Epson 603XL multipack also available, the 603 set contains a pretty humble amount of ink. This is however by design, as the black, cyan, magenta and yellow in the 603 range have been designed for light users of the Expression Home and WorkForce inkjet printers they are compatible with.The estimated page yields of the genuine Epson 603 multi-pack will still however be fine for most home users and has a reduced price tag to compensate. As this C13T03U64010 set is an original Epson product, you do of course get the best print quality available too!
