Flip Toys has launched its next Wooden Marble Run model called Coaster! This model brings the same fun STEM learning experience as the Spiral model but with a larger build and with more twists and turns. Wooden Marble Run products are a set of wooden construction puzzle toys, which require die-cut pieces to be assembled into a marble run. Propelled by either a solar panel or battery, this in-demand gift is the must buy product for kids age 8 - 88.
