These are Plarail toys that were included with McDonald's Happy Meals from September to October 2023. I am selling a set of 4, unopened. Also included are 2 rail sheets and 2 paper crafts distributed by Skylark. Since they are unopened, the contents are unknown. The Plarail toys are one of those listed in images 2 and 3, and the paper crafts are one of those listed in image 4.
