You show a beautiful wooden box, it seems to have a drawer with a knobv but when you pull it it does not open. You then introduce a special key and insert it in the keyhole and twist it to the left and right and pull it out again. When you now pull the knob the drawer opens, but when your audience takes a look inside the box there is only a keyhole – no lock! So, how to use? Maybe you can borrow an item from the spectator, a watch, ring, creditcard, etc. and place it in the box, close it and lock it with the special key. You then handover everything to the spectator and ask him to try to open it. They will not succeed. You take the box back from the spectator, put the key in the keyhole and the box opens and the item can be returned to the spectator! This is a very nice prop and combines a magic principle with a puzzle. Very easy to use. We supply the box, key and instructions.
