Manufacturer: Ickle Pickle Products, Inc.
A spectator selects one Sharpie from a wooden stand. Your back is turned when he selects his Sharpie. He then replaces his Sharpie into the stand. If you wish, a second spectator (and should you so desire - even a third spectator) can select a Sharpie and then replace it. You are then able to tell each spectator what marker he (she) selected.
Comes complete with 4 Sharpies (Red, Blue, Green, Black), wooden stand and instruction sheet.
