This is a Paper Copter paper toy, designed by Canon Papercraft. It is the second version, the first version is here: Canon Papercraft – Paper Copter. This paper craft is a paper version of the "taketombo," a traditional bamboo toy played with in Japan since times of old. Pull the string which is wound around the shaft, to make the propeller fly. The amount of curve in the wings and the strength you apply can change the way it flies, so you can have fun experimenting with it.
