Using this MierEdu pocket watercolour painting book is a breeze. First, grab a little water. Just dip your brush in the water and start painting on the special pages. The colors will appear right away! It's great for indoor play like in your living room or outdoor travel, for example, on a picnic. When you're done, you can tear off the pages easily because of the perforated or serrated edges. You can even cut and piece them together to make cool scene paintings. Make sure to keep the book dry when not in use. If it gets wet accidentally, let it dry thoroughly. It's for kids 3 and up, so adult supervision might be needed for younger children to ensure they use it safely.
