When do you need black refill ink?
Black refill ink is used to top up empty or nearly empty ink cartridges, which can save you a considerable amount on printing costs. This is especially useful if you regularly print black-and-white documents such as texts, reports or invoices.

Why this specific Kores ink?
This Kores G1638BK ink has been specially developed as a replacement for the original Epson T3591 cartridge. With a 50 ml capacity, you get a generous amount of ink that is suitable for multiple refills, depending on your cartridge size.

Compatibility with your printer
This ink works exclusively with the Epson WorkForce 4720, 4725 and 4740 printers. The ink is compatible with OEM number C13T35914010 (No.35XL), which means you get the same print quality as with original Epson ink, but at a much lower price per millilitre.

Practical tip for refilling
Make sure your cartridge is completely empty before you start refilling and work in a well-ventilated area. Keep in mind the ink capacity of your cartridge – never fill it beyond its maximum capacity. Store any leftover ink at room temperature and away from direct sunlight to preserve its quality.
