Quadrilla Twist & Rail Marble Run

The process of building the marble run is just as exciting as racing the marbles! Children will stack and connect these wooden pieces to build amazing structures, then send marbles zooming again and again. An irresistible, versatile activity for families and for independent play. Quadrilla wooden marble runs are designed for success, with graphic instructions for the simplest layouts, and notch-together pieces color-coded by function. Children will soon grasp basic construction principles and begin creating runs of their own design. Oppenheim Toy Portfolio Platinum Award. Set contents listed below.
