This box contains 18 boards for drawing and writing with the exclusive ergonomic pen provided.As the child completes the various activities, you simply need to turn the pen around and use the eraser on the other end to rub everything out. The indents on the pen make handling it correctly both easy and intuitive, and are also suitable for children who write with their left hands.
