Any small object, such as a dollar bill or ring, that you put in the box will magically vanish and then reappear!
Easy to do instructions included.
The more advanced magician may want to open the drawer of the box to show that it is empty. Then have a spectator select a card from a deck, memorize it, and then replace the card back into the deck. The deck may even be put back into it's case. The empty drawer of the box is now closed. A few magic words are said and when the drawer is reopened, the selected card is found folded up inside!
