One of the most interesting kinetic toys we have ever found. The first time the jaZams crew came across the multi-run we spend hours playing and experimenting with all of the parts. It has been a fixture in in our stores ever since. Children (and adults) will be fascinated by the never-ending ways of getting the various pieces down the run without running into each other. A jaZams favorite. WARNING: CHOKING HAZARD - Small Parts. Not for children under 3yrs.
