Useful Machines. Reusable Water Coloring Book

"Useful Machines" is not an ordinary coloring book, but a magical book for young artists. Boys will learn that they can draw and color not only with pencils, markers, or paints, but also with water. By running a wet brush across the paper, a bright picture appears before you. When the water dries, the drawing will turn black and white again, and it can be colored anew!
True magic! Easy? Yes! Fun? Of course! And also very useful: children will get an idea of shape and color, practice fine motor skills, and improve coordination. The technique of water coloring is so simple that even the smallest artist will create a beautiful picture.
For preschool age.
