Stop & Go - a short pause, and the marbles already can be released again to zoom through the marble run. With this expansion set, 2 stop points can be constructed, with the guidance of the building instructions. The stop points can be operated manually, and can be creatively integrated into the pre-built Fischer Technik marble run. With this set, the existing marble runs can be enhanced and the play value increased. Specifications: - Age: 7 Years + - Item Dimensions: 22.5 x 6.5 x 15cm
