Shinkalion Z 800 Tsubame Purchased 3 years ago, my child played with it for a while, but it's been sitting in the toy box ever since. There's likely some discoloration on the top of the main body due to sun exposure. I tried scrubbing it with a Melamine sponge, but it didn't come off, so it's not yellowing from dirt. One of the train connection parts has a widening (deformation). Please comment before purchasing if you have any concerns. Please understand that this is a used item. I'm also selling other Shinkalion items, so bulk purchases are welcome!
