Build and Rebuild The brightly colored big blocks easily slide, stack, and click together, providing hours of engineering fun for kids while helping to develop fine motor skills.

Funnel, U-Shape, L-Shape The funnel allows the ball to pass through one by one, while the U and L-shaped tracks allow the marbles to make 180 and 90-degree turns, respectively.

Why Not Use Glass Marbles? Glass marbles are much heavier than plastic marbles, which means they have too much energy and can pop out of the track when rolling down from a high place. This marble run set includes 4 colorful plastic balls.
