The popular paint-with-water activity books by Melissa & Doug. Simply colour in the pages with water and just like magic, the colours appear. Let it dry and start all over again.

All you do is fill the chunky water pen with water and colour in each page with the water. Watch the colours appear as you 'paint'. When the pages dry the pictures are erased and they can colour it in again and again. Kids will love it.

The pen is easy for kids to hold and stores neatly right in the front cover. Ideal when you're out and about or travelling, or just sitting quietly at home.
