FW Acrylic Artists' Ink, Cool Grey Opaque, 1oz Bottle
Brightly colored, water-resistant and non-clogging, these inks are made with pigments, not dyes, which gives them excellent tinting strength and good lightfastness properties (29 of the 30 colors are permanent-Flame Orange is moderately permanent). Use FW inks full-strength with brushes, airbrushes and technical pens, or dilute them for subtle tones. All the colors are intermixable and are water-resistant once dry. Opaque and transparent colors come in 1 oz. glass jars with glass dropper lids.
