More of a puzzle than an actual magic trick.
The box is handed to a spectator and they can clearly see a bank note inside (not supplied with trick!!!).
No matter how hard they try though, they CANNOT figure out how to get inside the box to retrieve the banknote!!!
Of course when you are handed the box, you show how simple it is.
EXTREMELY EASY TO OPEN ONCE FIGURED OUT!!!
Comes with FULL instructions.
