Make a hole through a banknote 'The last wonder of magic pocket. 
There are many great magical effects that give the illusion of a pen that penetrates through a bill without leaving a hole. They are known as John Cornelius 'pen through anything and perfect pen or Doug Edwards' pen-etration. The origins of these effects go back to wandering hole Hideo Kato for the Tenyo. 
And now, another masterpiece is born from the collaboration between Doug and Tenyo. 
The pen seems normal and you can use it to write normally. The really clever trick allows you to give it to control safely. 

Remember: there are no additional gimmick, is not removed and you do not add anything. We serve only the pen and ... a note!
