This pen, which looks very much like a small soldering iron, has a triangular section handle which makes it comfortable to grip and therefore easy to control. The handle flares out to form a guard to keep the fingers away from the hot bits of the iron. There are six interchangeable bits supplied with the pen, which allow a range of graphic effects to be achieved and an additional set of patterned ones is also available. All you need to add is a bit of creativity!
