st@r ink 522 Replacement Ink Bottles, 6-Pack for EcoTank Printers

Fit and sizing

For routine home, school, or small-office printing, this six-bottle ink set is made for compatible Epson EcoTank printers. It works with the ET-2400, ET-2720, ET-2800, ET-2803, ET-2840, ET-4700, ET-4800, and ET-4810. Matching the printer model before refilling helps ensure you choose the right replacement ink for its refill system.

The set provides black, cyan, magenta, and yellow ink, with three black bottles and one of each color. That mix is useful when text-heavy printing calls for extra black ink alongside color for charts, graphics, homework, and everyday photos.

Why it’s worth it

Refill bottles let EcoTank owners replenish their printer’s ink tanks directly, rather than replacing conventional cartridges. The bottles have an auto-stop nozzle design: insert one into the matching filling port and allow the ink to flow without squeezing. This straightforward process is practical for scheduled top-ups at home or in a shared workspace.

The water-based dye ink is described as quick-drying and is intended for color printing as well as everyday documents. A set of six bottles also gives frequent printers a multi-color supply on hand, including three bottles of black for common text-printing tasks. Each bottle holds 70 mL, and the stated yield is up to 6,000 pages per bottle at 5% coverage on A4 paper, actual results depend on print coverage and use.

Buyers commonly highlight ease of refilling, printer compatibility, and long-lasting use. Those comments reflect customer impressions, while the practical appeal here is the direct-fill format and the four-color set. Compared with buying ink one color at a time, this pack provides black, cyan, magenta, and yellow together, with extra black for everyday printing.
