Using this coloring book is easy! Just grab one of the 8 metallic - ink gel pens and start coloring on the 60 black pages. Let your imagination run wild as you bring Isadora's story to life. When you're done coloring, put the pens back in the box to keep them organized. Remember to keep the coloring book away from water as it might damage the pages and the ink of the pens. If the pens start to dry out, try pressing the tip on a piece of scrap paper a few times. Enjoy your creative coloring time!
