Now you can express yourself without the mess thanks to the Crayola Colour Wonder PJ Masks Colouring Pages. The five included markers are filled with special ink that only appears on the magical Colour Wonder paper. That means it won't appear on furniture, skin or anywhere else that might upset grown-ups! This awesome set comes with 18 pages of your favourite PJ Masks characters to colour, so you'll be busy for hours to come! Check out the rest of the Colour Wonder set for even more cool pages to customise. Fun for artists aged 6 and over.
