Performer displays a triangular box on both sides. He then opens out the front to display it completely empty inside. The audience can see the entire inside of the box...and the middle section...through a cut out in the panel which they can see right through. The box is again closed and a variety of items like silks, sponge balls, ribbons and streamers are produced. Sturdily made, attractively decorated and supplied complete with illustrated instructions and various ideas by Ian Adair for its use.
