Hanayama Cast Puzzle: Mobius (level 4)
Dutch inventor Oskar Van Deventer designed the Mobius puzzle based on the Mobius strip - a never ending loop where one side twists elegantly into the other side, without ever crossing an edge. The inside becomes the outside, and the outside becomes the inside. Add a maze to the strip, and the challenge begins! Can you take it apart? Now put it back together!.
