Welcome to the colourful world of Rainbow Dots, a brand new MESS-FREE and REUSABLE activity book series for little artists. All the friendly roar-some dinosaurs are missing their rainbow dots. Can you help find them? Use the special water stamper pen to stamp the white circles inside the book with water and discover hidden dots of rainbow colours on each right-hand page. Using the book is 'dots' of fun and super-simple! Just unscrew the stamper pen tip, add water, then screw the tip back on, and your stamper pen is ready to use! The book is 100% reusable too - once the water dries on each right-hand picture, you can paint the pictures again and again! Designed specially for little artists aged 3+ to help boost their pen control through holding the stamper and building hand-eye coordination from holding the stamper in place and stamping the white circles.
