Unlike other Rube-Goldberg-type toys, KEVA Contraptions employs snugly fitting, non-warped pieces that don't have breaks or skips, meaning the ball will never move unpredictably or careen off. Guaranteed to entertain rather than frustrate! With no glue or connectors needed, the KEVA Contraptions set is ready to play right out of the box. Forget the hassle of having to round up a laundry list of non-included tools. Simply unpack and build! Each set comes with 2 balls.
