This unusual packing puzzle is restricted by a clear acrylic cover that only has a small hole in it. The pieces must therefore not only fit into the frame, but they must also be inserted in the correct order in order to solve the puzzle.
Made in laser-cut wood, acrylic, and stainless steel by Jean-Claude Constantin. Jean-Claude Constantin lives in Germany, where he designs and manufactures many different wood and metal puzzle, as well as magic tricks.
