PILOT Precise P-500 Extra Fine Point Gel Ink Rolling Ball Pens - 12 Pack (38600) - Black Ink for Writing, Note Taking & Office Work - Smooth & Precise for Students, Professionals & Artists

I have used this pen for years. I like the small tip which allows me to make notes in my checkbook when I'm balancing our account against the statement. The .5 is great for puzzles. It is a smooth writing pen, unlike some of the later models that have tried to compete with this particular pen.
