Canon 351 and 350 ink cartridge 5-color set, ideal for improving print quality. - Brand: Canon - Model: 351, 350 - Colors: Black, Cyan, Magenta, Yellow, Gray Purchased in September on Amazon for 5100 yen. I accidentally bought the wrong set, and realized my mistake after installing the blue cartridge. The blue cartridge has been opened, but I think it's still usable. Installation deadline is July 2027. Thank you for looking.
