The Lamy Accent multi-pen is four pens in one! It comes with three color ballpens and a pencil in one pen. It has a balance mechanism, so whichever icon you look at whilst depressing the button is the one which comes out to use. Multi pens such as these are a fantastic business tool for people who have to constantly change colors, highlight, edit documents or use a pencil.......and the Lamy is the best one on the market!
