GloGlo Inkoos bring kids designs to life - even in the dark. As with all inkoos, kids can draw and decorate on them with the included washable markers. But when the lights go out, their cool glow-in-the-dark patterns are revealed. Then kids can draw even more glowing designs with the special light pen. Each GloGlo inkoos includes 3 clip-on, washable markers plus the GloGlo light pen. Choose from 3 styles. Machine washable.
