This is a Shinkansen (bullet train) set featuring the 500 series and 700 series trains. They've been stored in a closet for a long time, but I don't remember playing with them much, so both the box and the contents are surprisingly clean. I don't have any new size-5 batteries, so I can't confirm if they work. The batteries inside are probably dead. Perfect for collectors! I plan to ship them in simple packaging. I'm also selling other items in various genres. Price reduced.
