EPSON Epson Ink Cartridge Recommended Use-by Date: October-December 2015 They were perfectly usable because they were completely sealed. Although some have no outer box or the outer box has some dents, all are unopened. I used them at home for work, but I no longer need the cartridges due to a printer malfunction, so I am selling them together. Please refer to the second image for the contents. Please refrain from purchasing if you are concerned as they have been stored at home. ▪︎Additional Information▪︎ I found one magenta and one dark yellow, so I will include those as well.
