4 Dimensional Trunk by Tenyo Magic

The production of a full sized bowling ball from a thin briefcase created J. C. Doty became one of most popular opening effects for stage magicians. It spawned a few interpretations including Kevin James's Bowlarama.

The 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.
