HUB 12 Marble Set

The bright green and blue marbles really pop as they race down the track, and each one glides perfectly without getting stuck. My kids have been building different runs all afternoon.

My nephew’s building runs are so much smoother now that he has these—the weight is just right for staying on the track. The four colors make it easy to sort and plan out different sections of the course.

The colors are super vibrant and my kid loves sorting them before each run. They roll smoothly through the track without getting stuck, which makes all the difference in building a fun course.
