The EC Colouring books from Australian brand EC are not your normal colouring books. The pages of these books are as thick as cardboard. You could even paint on one side and still be able to use the other. Unlike other colouring books, if markers are used you will not be able to see anything coming through to the other side of the page. So you get full value from every page.
20 Page, A4 in size available in Dinosaur, Fairies, Farm Life, Sea Life and Princess.
