I've included the photos in the second image. To prevent water damage, I will put them in nylon and seal them in a cardboard box. I bought a lot of these because the motors in the drive units were often defective, but my child has lost interest, so I'm selling them. I only kept the ones that worked. Please note that some may have stopped working during storage, so no claims or returns are accepted. They are almost unused as I used them to check the operation. I will pack the curved rails and the front and rear cars of the Nozomi Yamanote Line to the limit of a 74cm box. It is also possible to reduce the curved rails and add a tunnel. Please comment if you would like that (see the third image). Thank you for looking.
