I am selling these items because I no longer need them. There is no case. The 5000 and 8000 models seem to have been used very little. The 10000 model seems to have been used to a moderate extent. Please check the images. I do not know the product numbers. There are no accessories. The tracks are not included. Only the train cars themselves are included. Since these are used items, there may be small scratches, dirt, or missing parts. Please enlarge the images and examine them carefully before making your decision. We cannot accept any opinions or returns after delivery. Please purchase with your understanding. Shipping will be via Nekopos. Please refrain from purchasing if you are a nervous person, take a long time to confirm receipt, or are not good at communicating via comments. If the shipping address is in a remote island or other area where delivery takes a long time, please consult with me before purchasing. We are looking forward to your purchase if you understand the above.
