This is the Corocoro Coaster L. It's like a Pythagoras Switch, allowing you to create your own custom course and roll a ball down it. All the parts are included, but please note that the box and instruction manual are not included. I believe there are no noticeable scratches or stains. It has been wiped down with a disinfectant wipe. Product page: https://www.toyroyal.co.jp/products/intellectual-toy/block/3487.html
