3D Puzzle and Thinking Game Purchased new around 2008, used sparingly, and not used for many years. The puzzle has minor scratches. The instruction manual has yellowing and stains. This is a puzzle for adults. How about some brain training? I am also listing other puzzles from the same series. The instruction manual will be folded to fit the shipping size, placed in a plastic bag, bubble wrap, and cardboard, and sent via Yu-Packet Post. The puzzle will be disassembled and packaged. Please excuse any folds or wrinkles. Please read my profile for precautions to prevent any trouble. Thank you for looking.
