The Hubelino Mega Building Box Set is a marble run set designed for young engineers and builders who love marble mazes, ball runs, and toy building sets. With 585 pieces, including marble track components, base plates, and marbles for kids, this STEM toy challenges children to design, build, and race their own marble runs. Perfect for kids building toys, this marble race track set features six unique extensions, allowing endless configurations for exciting marble races. The included instruction book provides three giant assembly ideas, including a ball maze and marble race track, helping kids explore engineering toys in a fun, hands-on way.
