FW Pearlescent Inks create dazzling effects to illuminate and accentuate a variety of surfaces. These acrylic-based inks are water soluble when wet, but dry to a water-resistant film. All colors are fully intermixable, permanent, translucent, and offer high lightfastness. FW Liquid Inks provide a breakthrough in color technology for limitless creative potential and works best when put down freely rather than applying successive layers. Apply to paper, board, wood, leather, and, to a limited degree, glass and ceramics.Due to large partcile size of pearlescent pigments, they are not suitable for fine line airbrush nozzles, technical pens, fountain pens, or paint markers. Packaged in a 1 oz. bottle.
