Review on Ink Revcol 101/103 for Epson L1110/ L3150/ L5190, 4 colors of 70ml, Dye (Premium) by Wiktor Krzysztof Kor ᠌

To avoid getting one's hands soiled when restocking the printer, this refilling mechanism was developed. Additionally, opening the bottle requires getting your hands dirty. When the gasket is taken out from under the cover, they have to go through more pain. Once you have gathered everything, you can proceed to loading the printer. However, in theory, you could gain an extra five minutes of height and experience some dirtiness for that money.
