The Epson 786XL Black, Cyan, Magenta, and Yellow ink cartridges are genuine/original products manufactured by Epson. These ink cartridges are specifically designed for use with Epson printers, such as the WorkForce Pro WF-5110, WF-4630, and WF-4630DWF models. With an expiration date of June 2019 on the Black, Pink and Yellow catridges and October 2020 on the cyan, these ink cartridges provide reliable and consistent performance for your printing needs. The Black ink box has come apart at the bottom and is open (see pictures) but the cartridge is sealed in the plastic and unused.
