GraviTrax FlexTube lets you bend, twist, and connect different levels of your marble run. Each tube can be shaped into S, U, or angled curves, adding dramatic drops and turns to any GraviTrax starter set. Includes 4 FlexTubes and 4 height tiles, ages 8+.
GraviTrax FlexTube is an accessory pack that helps your marbles change direction and level in style. The four flexible tubes can be bent into S shapes, U turns, or angled connectors, so you can weave tracks together, loop around obstacles, or bridge gaps. With the included height tiles, it plugs neatly into any existing GraviTrax layout for more vertical, fast paced builds.
