Higgins Dye-Based Ink is a student grade ink that is perfect for application on paper and board (8 colors work well on film). Vivid, transparent washes as brilliant as liquid watercolor can be mixed or diluted with water to produce an infinite range of shades and hues. For use with brush or dip pen, these vibrant inks are available in 16 colors. They dry slowly and have a matte to semi-gloss sheen; 2 out of 16 are waterproof (Neutral Gray and Russet). The signature Higgins ink bottle with dropper makes this ink easy to dispense without the risk of spilling.
