Each of the Epson black, cyan, magenta and yellow ink cartridges we have in the genuine Epson SJIC30P range is the real thing and comes with the manufacturers seal of approval. Huge in size and containing a full 294ml of yellow ink inside, the original Epson C33S020642 is great value for a brand new cartridge.The Epson SJIC30P(Y) was designed initially for use in the ColourWorks C7500G exclusively, but you can find any other compatible printers that have since been released, elsewhere on this page. Epson fully guarantee this C33S020642 yellow ink cartridge directly, but with the quality of manufacture present, this is hardly ever needed.
