A sleight of interest to see. learn at least 1 day to practice. Remarkable that a pen can penetrate paper money or coin, the coin into a different coin with a one-time beat with this pen. This illusion is one of the Close-Up is very incredible. There are several models Pen penetrate money but this one is the best and only use a pen (No Switches) and the same pen can be freely submitted for review in the audience and able to write like a normal pen. Complete and ready for use with the instructions with color photos for four miraculous effects stunning. Highly Recommended.
