American magic creator J. C. Doty became famous for his production of a full-sized bowling ball from a thin briefcase that was much too small to contain the ball. 4-Dimensional Trunk is a light-weight version of the same trick that enables you to perform this powerful effect at any time. A plastic golf ball is included in this package so that you can start performing right away. You may choose to substitute the plastic ball for a real golf ball that you supply.

English instructions included.
