V4ink T664 XL 4PK ink cartridges Black Cyan Magenta Yellow

Four-colour refill kit for EcoTank printers

This four-bottle set supplies black, cyan, magenta and yellow ink for Epson EcoTank and WorkForce tank printers. It is intended for owners of listed models who refill their own tanks rather than buying sealed cartridges. The bottles are manufactured new and designed to be recognised by the printer's ink-level system.

High-yield output under continuous printing

Each black bottle yields approximately 4000 pages and each colour bottle yields approximately 6500 pages at 5 % coverage on A4 or Letter paper. These figures reflect sustained printing rather than a short burst, so high-volume users can plan refill intervals around predictable page counts.

Clean handling and stable ink flow

The ink formulation is designed to flow cleanly into EcoTank reservoirs without clogging or leaking during normal refill operations. No special ventilation or temperature controls are mentioned, and the bottles are sealed for storage until needed.
