Let your creative imagination go wild with the new Super Rainbow Deluxe. Simply fill the Aquadoodle pen with ordinary tap water, run the nib over the magic mat and see the colours appear. Any water that does run off the mat, runs clear. No mess, no stains, nothing to worry about. As your drawings dry, designs fade away, ready for the mat to be used again, over and over again. When you need to, just refill the Aquadoodle pen with water and go again. Included in the set is a special paintbrush that lets you make broader strokes, as well as three stampers for added mess-free fun. When you have finished, mat folds up for easy storage.
