I don't know the details of the rails. The outer box has some tears. Also, there is dirt and scratches on the outer box, the transparent case, and the rails. Here is the information written on the outer box, etc.: * Blue outer box Shinkansen Okayama Opening Commemoration (Sanyo Shinkansen Rail) 1972.3.15 * Transparent case containing the rails Sanyo Shinkansen Opening Commemoration - Okayama Transportation Exposition 1972.3 * Sticker on the rails Sanyo Shinkansen Rail (Model) Shinkansen Okayama Opening Commemoration Okayama Transportation Exposition 1972 That's all. This is an old, used item, so please understand. I plan to wrap it in bubble wrap and ship it via Yu-Packet Post.
