Pearlescent inks produce a shimmering pearl effect. These acrylic based inks are water soluble when wet, but dry to a water resistant film. All colors are good to extremely lightfast. This breakthrough in color technology offers almost limitless creative potential in areas not normally associated with inks. Apply to paper, board, wood, leather, and, to a limited degree, glass and ceramics. Use with dip pen, ruling pen, or brush. 1 oz. bottle.
