Cardboard 3D puzzles

Cardboard

— the material used in a rather unusual variety of puzzles — figures of complex shape (for example, in the form of a character's head from a movie), assembled from separate layers of cardboard. It looks like this: sheets of cardboard are alternately put on a vertical stand; superimposed one on the other, they form a figure. In other types of puzzles, this material is practically not found.
