Thank you very much for your interest! Masudaya's Panel World Runs! D51! Steam Locomotive. This is a set of 8 panels and a steam locomotive. My child has played with it a few times. All the parts are included and can be played with without any problems, but since it has been used by a child, please refrain from purchasing if you are concerned about the details. The operating sound is very quiet, and there are no small parts, so it's easy to clean up. It runs on one AAA battery. It will be shipped without the box, and the instruction manual will be included. If you would like the box, it will be an additional 400 yen, so please contact me before purchasing. The box may have signs of being opened, so please understand this. (It does not affect storage)
