These are items my child collected when they were little. Some of the wind-up mechanisms are a little sluggish. I'm not familiar with trains and bullet trains, so I don't know the names of most of them, except for the famous ones. There are some rare items, such as a gold locomotive. These were toys my child played with, and they have been stored at home for a long time, so there may be some dirt, discoloration, and paint chipping. Please feel free to comment if you have any concerns. Please purchase with the understanding that these are used items.
