Fun and enchanting colouring book with a treasure hunt-themed picture. Fill the pen with water and use it to reveal hidden pictures. Fill the pen with water and start drawing. Colours and patterns start to emerge when they are watered with the pen. When the paper dries, the pictures disappear. They can be redrawn over and over again. Water magic books are easy to take on vacation or car rides because they are small but sturdy enough to be drawn on. One pen is enough to colour all pictures in a book. This drawing technique develops a child’s understanding of different types of drawing and the relationships of different shapes. There are 6 pictures in this colouring book. Have fun drawing. Suitable for children age 3 and up.
