The set Happy consist of 3 brightly coloured Moonlight gel pens to leave a colourful, fluorescent mark that’s uniquely your own. The collection includes Fluorescent Yellow (403) , Fluorescent Orange (405) and Fluorescent Green (427). Gelly Roll Moonlight® has the brightest and most vivid colours of the Gelly Roll® family. The creamy, smooth, opaque ink is perfect for drawing, doodling and colouring. All colours are bright on white paper and produce outstanding effects on black paper, and the fluorescents will glow under a black light source. The Sakura Gelly Roll contains special water-based pigment gel ink to give bright, intense colours which never fade. Thanks to the unique gel ink technology, the ink flow from the pen is always constant, without exerting any pressure. Moonlight Gelly Roll pens are available in a collection of 10 vivid colours.
