I am selling this because it didn't fit my EW-056A printer. This is a 4-color ink cartridge set compatible with Epson printers, designed to achieve high-quality printing. - Model: MED-4CL (Medamayaki) - Set Contents: 4-color set (Black, Cyan, Magenta, Yellow) - Compatible Printers: EW-056A, EW-456A - Product Features: Epson ink cartridges This is an ink cartridge set for home printers. There are a total of 6 cartridges: 3 black, 1 cyan, 1 magenta, and 1 yellow. However, one of the 3 black cartridges has been opened. (See photos 18-20) As a temporary measure, the ink part has been sealed with cellophane tape, but the opened cartridge may not be usable. Please understand that one cartridge has been opened and that this is compatible with the listed printers before purchasing.
