I only confirmed its operation once, and the main unit is practically unused. There is a part of the box that was torn when I opened it. There are no scratches or stains on the main unit at all. Therefore, I have listed it with the description "Like new." This is a miniature of Howl's Moving Castle that moves with a spring mechanism. When you turn the knob on the back of the main unit clockwise, it moves forward as if it were walking, while moving various parts.
