Choo-choo! Parents will love this 2-in-1 train set and kids will enjoy being the engineer on their self-built railroad! Create a track in the sand with one side of the roller and then turn it over to the eraser side and “pave” it smooth. Hook up the locomotive engine, flat-bed, and tank wagon rail cars and off you go. Children can even use the set to create an infinitely-long train brigade by filling the engine and car molds with sand! For age 2.5+
