3D Puzzle and Thinking Game Purchased new around 2008, used sparingly, and hasn't been used for many years. The puzzle has minor scratches and black marks (from the manufacturing process?). The instruction manual has yellowing, stains, and wear. This is a puzzle for adults. How about exercising your brain? 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 a cardboard box, and sent via Yu-Packet Post. The puzzle will be disassembled for packaging. Please be aware of potential folds and wrinkles. Please read my profile for any potential issues. Thank you for looking.
