I used to buy and play with these when my children were small. They are die-cast Shinkansen model trains from nearly 30 years ago. I believe they are now discontinued, and few remain. I took photos with a measuring tape for size reference. The models are not to scale, to allow for consistent lengths. Please see the photos for the condition. Considering they were played with by children, I think they are in good condition with few noticeable scratches or stains. There are magnetic couplers at the front and rear of the cars. They connect using the S and N poles of the magnets, but the front-to-front and rear-to-rear connections will repel and not connect. The coupler on the lead car can be stored under the body (photos 7 and 8) and pops out with the operation of the gray switch. I will wrap both cars in bubble wrap for shipping. I plan to use Yu-Packet Post Mini. Please understand that these are used items that have been played with by children before purchasing.
