This regular looking pen can be used to write with, then can be pushed through a dollar bill, any important paper, even a coin or a glass- without making a hole! The pen can clearly be seen sticking out of the paper on both sides. And while it is stuck through the paper, you can move the pen and the "hole" around! As you remove the pen, it makes a distinctive ripping sound- but the paper is unharmed! Really excellent! Made with an ordinary black rollerball pen, just like those found in office supply stores- or on someone's desk!And this pen comes with DVD instruction!
