Gimpy’a Light Heavy Shipping Box: perfectly constructed

This is produced by Gimpy and sold through Stevens Magic.  It is a wonderful concept.  An ordinary looking cardboard box turns into a light and heavy chest.  The box is brilliantly conceived to hide the gimmick. Spectators may look into the empty box with nothing to find.   The box is a very innocent looking cardboard box that can easily be picked up by one spectator but becomes impossible for another to lift.  Comes with  a Demo DVD and instructions.  This is new never used. Sells for $295.
