I am selling this because I accidentally purchased it. I opened the cyan and magenta cartridges, but they cannot be used because an error occurred when I set them in the printer, so the ink has not been used. When shipping, I will flatten the box. Please understand. This is a Canon 6-color ink cartridge set, including PG-350 and CL-351, compatible with Canon printers. - Brand: Canon - Model: PG-350, CL-351 - Colors: Black, Cyan, Magenta, Yellow, Gray, Black - Package Contents: 6-color set - Compatibility: For Canon printers Thank you for looking.
