Gelly Roll Moonlight® has the brightest and most vivid colors of the Gelly Roll® family. The creamy, smooth, opaque ink is perfect for drawing, doodling and coloring. All colors are bright on white paper and produce outstanding effects on black paper, and the fluorescents will glow under a black light source. Gelly Roll Moonlight® also works like a paint pen on colored papers, vellum and photographs.
