The lifter expansion set takes your marble run experience to a whole new level with over 25 additional elements. Once the marble reaches the bottom, raise it up to 2 levels higher using the lifter accessory: a button-operated elevator. Experiment with additional tracks, height tiles, and one transparent level. Combine with the Gravitrax Starter Set and test your skills to see how long you can keep the marbles rolling.

NOTE: This is not a stand-alone product; it is designed to be used with the Gravitrax Starter Set, product # GX275977
