Create your own 3D figures with the special 3Doodler pen. With this pen you can literally draw in the air. Insert a color stick through the back of the pen. This color comes out liquid on the other side, so you can draw. 3Doodler uses special plastic that melts at a very low temperature, making it safe for children. The included Design Book contains 12 different designs, such as the Eiffel Tower and a cheerful flower.
