Proven design, been made for years. The only "sticking point" is an actual "sticking point." The 2 horses are nested together and the way to separate them from one another is not immediately obvious. But just mess with them until they separate, at which point you'll see how they fit together. These LOOK flimsy in the picture, but no; they're plenty sturdy and tough.. John. MD. Tue Aug 31 2021
