The Barva E101-558 is a black pigment-based ink designed specifically for use in Epson inkjet printers. This 100 ml bottle serves as a compatible replacement for the T03ZV1 (101 BK) cartridge, making it a practical choice for those using the Epson L series, including models such as the L4150, L4160, L6160, L6170, and L6190. Because it uses pigment ink rather than dye, your documents will have sharper text and better resistance to smudging or fading over time. With a pack size and capacity of 100 ml, a single bottle provides enough ink to print approximately 1100 pages, which is helpful for maintaining a steady workflow in a home office or small business environment without needing frequent refills.
