3D Puzzle and Thinking Game Purchased new over 20 years ago, used sparingly, and not used for many years. Condition: Puzzle has minor scratches, is slightly faded, and has no instruction manual. This is a puzzle for adults. I tried it without the instructions and was able to solve it! The photos show the pieces disassembled, which I have put together. Please refer to the photos if you are unsure. How about it for a brain workout? I am also selling other puzzles from the same series. It will be sent in a plastic bag, bubble wrap, and an envelope via Yu-Packet Post Mini. The puzzle may come apart during shipping, please be aware of this. Please read my profile to avoid any problems. Thank you for looking.
