Demon Improved Note Tube

The magician asks a spectator to help and borrows a bank note off them, having first made sure that the serial number has been noted. The bank note is covered with a handkerchief and given to the spectator to hold. The note vanishes and the magician then produces a small tube and gives it to the spectator. The spectator opens the tube by twisting out a bolt through the lid and then unscrewing the lid. To the surprise of everyone, the spectator finds their note rolled up in the tube. The black Bakelite tube has a Demon head trademark inscribed on the bottom of the tube. Complete with instructions.
