Glow in the Dark - Ocean, from Europrice, is a coloring book with a marine life theme and phosphorescent illustrations. The illustrations in this Glow in the Dark collection absorb light when exposed to a light source and glow in the dark after the light is turned off, combining the magic of phosphorescence with the traditional pleasure of coloring. Europrice is the leading children's book publisher in Portugal, with a catalog designed to stimulate creativity and motor skills through pencil and paper, rather than screen. It's a prime choice for children fascinated by whales, fish, and sea creatures that gain an extra glow when the lights go out.
