This is a McDonald's Happy Meal toy, "Doraemon's Exciting Science" - "Rotating Disk! Time Machine". There are signs of use and minor stains. It has been displayed, so it has some dust on it. I will wipe it down as much as possible before shipping. Please inquire if you understand. When you run the time machine, the disk behind Doraemon rotates. This toy teaches how power is transmitted using gears. Thank you for looking.
