Adairs Triangular Production Box

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