This is a wooden toy train. I received it as a gift when my child was small and they used to play with it. There are no noticeable stains, but it has been stored at home, so please refrain from purchasing if you are concerned. ◯ It sticks together with magnets, so you can connect them or stack them in two layers to play. ◯ I think it would also be nice to display it in a room as an object.
