What is the best pen to write on your skin?  I want to take notes on my hand so I can cheat on my test.

It is best to use a water-resistant ink pen when writing on your skin. Some popular choices are the Pilot G-TEC-C4 747 Rollerball Pen, the Flairs Pen Fine Tip Marker Pen, and the Sharpie permanent marker. Be sure to select a pen with water-resistant ink that will not smudge or wear off after a short amount of time. It may also be helpful to clean your skin before writing to remove any dirt or oils that may interfere with the pen’s grip.
