Thank you for viewing. I used to use a Canon printer MG7530, but I'm selling these ink cartridges because I no longer need them after replacing the printer. Item: Set of 9 ink cartridges. Colors/Contents: 350XL Black x 1, 351 XL Black x 2, 351 XL Gray x 2, 351 XL Cyan x 1, 351 XL Magenta x 1, 351 XL Yellow x 2 *These are not genuine products. *The first 6 and the last 3 cartridges are from different manufacturers. Please check the photos for details. Thank you.
