Universal Epson Pigment Ink refill pack - compatible with pigment ink based Epson inkjet Printer(s) (such as the Epson WF-3620, WF-3640, WF-7110, WF-7610, WF-7620 and many more). Includes 100ml refill bottles (1 each for Black, Cyan, Magenta, Yellow) with smart pouring spouts. This is also a perfect refill pack for use with Continuous Ink Systems (and with the smart pouring spout, you can pour ink directly into the fill holes of all continuous ink systems). Only the ink is included (no additional tools or instructions are provided). This refill pack is intended for refillers who know how to refill their Epson ink cartridges. With the 100ml per color included, you can refill most Epson cartridges 5-8 times each per color. This is pigment ink made to compare as close as possible to the OEM Epson ink, and is also UV resistant and archival.
