This is a Sekiguchi wind-up toy. When the spring is wound, the body and arms move. I have confirmed its operation, and it works without any problems at this time. It is an old item, so there are some stains and scratches. Please check the condition carefully in the photos, etc. Please understand that this is a vintage item before making a purchase. Please note that this is an old, used item, so please refrain from purchasing if you are sensitive to such things or if you are looking for a perfect item.
