The Koh-I-Noor® line of Universal® inks was first developed for use with technical pens. The dye base eliminates the potential for cloggling the finest nibbed Rapidogaph® Pens, and offers an intense color laydown. The shellac used in our ink formula creates a waterproof ink that can be used on both paper and film substrates. The black ink is highly opaque, and the white is semi-opaque, while the colored inks are semi-transparent.

Not only are these inks ideal for use with Koh-I-Noor® technical pens, but they can also be used with airbrushes, crowquill pens, and paint brushes. Cleans up easily with the Koh-I-Noor pen cleaner and Rapidoeeze® pen cleaner system. The 1 oz. size has a convenient dropper spout ideal for filling technical pens and art markers. The larger size bottles of black ink have a flip up spout for controlled filling and mixing applications.
