The release date is unknown, but this is a "Doraemon Bubble Train," an amusement-only prize. It's quite old and seems to move while blowing bubbles electrically. It's new and unopened, and the operation hasn't been confirmed. There are two types, with different wheel colors: red and yellow. This item is red. The images show the entire condition. Although it's new and unused, please refrain from purchasing if you are sensitive to such things. This is from a collection. No returns or exchanges, please!
