A cube on a string runs freely down. At the command, it stops at whatever position it may be on the string and stays there until told to go to the bottom.
 
CONDITION NOTES:  A beautiful piece of magic history. This set appears unused and remains in excellent condition. It features a unique olive drab green color and includes the original instructions printed on very thin, tissue-style paper, which are also in excellent condition. The box shows some light age discoloration but is fully intact and displays well. A wonderful addition to any magic collection.
