With a choice of 2 designs, Unicorn or Dinosaur, these magic colouring books are a great way to keep the kids entertained on a rainy day. Just grab a paintbrush and add water. As you paint the water on to the pictures, the colour magically appears. As the paper dries, the colour will disappear, and the pictures can be painted again. A great way to let the little one’s ‘paint’ with no mess to clear up afterwards.
