Canon printer ink cartridges, a 5-color set of 351XL. (Only the 350 from the set has been used, so the box is for 6 cartridges, but this is a 5-cartridge set.) The expiration date has passed. The printer suddenly broke and I stopped using it. The box will be flattened for shipping. (If you don't need the box, I will ship only the ink cartridges.) Please understand the above before purchasing. Thank you. Canon Model Name: BCI-351XL+350XL/6MP Multi-pack, High Capacity
