Expression ET-2500
The Epson Expression ET-2500 is a first-generation EcoTank all-in-one, and its ink is the 664 family in all four positions: black (T664120), cyan, magenta and yellow — every bottle 70 mL, black rated up to 4,000 pages and each colour up to 6,500. Clever Supplies compatible 664 bottles below are keyed for the ET-2500's tanks and carry a lifetime warranty.

ET-2500 Ink: The Full-664 Original Epson's ET-2500 page is the reference spec for this family: Included ink — 1 bottle 664 Black, Cyan, Magenta, Yellow (70 mL); Replacement Ink — 664 Black, Cyan, Magenta, Yellow (ISO Yield, Epson Methodology — Black: 4,000, Color: 6,500). Those conservative figures are the ones our product pages carry for the whole 664 family, even where a later model's page prints higher numbers.
The ET-2500's generation is also where EcoTank naming gets treacherous: its younger sibling ET-2550 is full-664 like this one, but the ET-3600 down the shelf runs a split system (774 black, 664 colours). Your model is unambiguous — all four bottles on this page are yours, including the black and the 4-bottle set.
Singles or the set, every Clever Supplies 664 bottle carries a lifetime warranty and 1-year free returns.
