Genuine Canon ink cartridges. The expiration dates are: multi-pack - September of this year, magenta - October of this year. The two black cartridges don't have boxes, but I believe they expire in September as well, since I bought them at the same time. I no longer need them because I replaced my printer. They were stored in a drawer indoors. They are new and unopened, but please understand that they have been stored at home. I will ship the ink cartridges and the folded boxes separately. If you prefer to receive them unopened, please let me know in the comments beforehand.
