Total of 6 cartridges: PIXUS 351. All are unused. Details are as follows (dates are the installation deadline): Yellow Opened, unused, high-capacity type, 2026.3 Magenta Opened, unused, high-capacity type, 2025.9 Cyan Opened, unused, high-capacity type, 2025.10 Black (PGBK) Opened, unused, high-capacity type, 2026.1 Black (BK) Unopened label, no box, high-capacity type The installation deadline cannot be confirmed due to the loss of the box, but the purchase date is the same as all other colors. Gray Completely unopened (never taken out of the box) Only gray is the standard capacity type, 2025.9 I mistakenly purchased the wrong model number, and without realizing it, I opened all colors except gray and PGBK. Since the model number is different and they cannot be used, all are completely unused, including those that have been opened. However, please understand that they have been opened before purchasing. Also, except for BK, the original boxes are still available, so you can confirm that they are genuine Canon products, high-capacity, and within the installation deadline. If you have any questions regarding the product condition, please feel free to comment. We are also happy to discuss selling them individually.
