Pythagoras Ball Coaster DX and others A large volume of over 89 parts! This is a set of two types: Pythagoras Ball Coaster DX and a set worth 6000 yen. Pythagoras Ball Coaster DX has a box. All parts are included. Neither has an educational play guide. We will pack both together, so different types of parts will be put in the Ball Coaster DX box. Parts that don't fit will be put in another box. Please note that the packaging is not perfect as it is done by an amateur. We will include some anpan balls (same size as the original balls). Some parts have scratches, stains, and yellowing, but I think they are still usable. My daughter is very serious, so the condition is good considering how much she played with them. I bought them 5 years ago and stored them in the closet for about 2 years without playing with them. She played with them quite a bit for 3 years. If you are concerned about minor details, please refrain from purchasing. Please read the profile for requests, etc., before considering your purchase.
