Two sets of EPSON 4-color ink cartridges. Recommended expiration dates are December 2020 and October 2018. Both are past their recommended expiration dates. One has a recommended expiration date of October 2018. The other has a recommended expiration date of December 2020. The one with the October 2018 expiration date has its box lid open, but the film on the ink cartridge itself is still intact. The one with the December 2020 expiration date is unopened. When shipping, I will pack 8 ink cartridges removed from their boxes, and one empty box. (I thought the empty box might be useful because it has the instructions and other information.) These are genuine EPSON products, and they cost about 4000 yen per pack on Amazon. They are actually worth about 8000 yen. However, because they are past their recommended expiration dates, I am offering them at a lower price. I hope you understand this. - Brand: EPSON - Pack Quantity: 4-color pack - Set Quantity: 2 sets - Recommended Expiration Date: December 2020 - Recommended Expiration Date: October 2018 Recorder Compatible Models PX-048A PX-049A Model Number RDH-4CL Recorder Black RDH-BK Recorder Cyan RDH-C Recorder Magenta RDH-M Recorder Yellow RDH-Y Thank you for looking.
