This is a PSI Olympian rollerball, in chrome, and is my first. It's .655" at the center band, and is the biggest pen I've turned. It requires 31/64" and 33/64" drill bits. The kit is inexpensive at only $10, and some may think it's cheap. Yes, it has a lot of plastic parts, but in spite of that, I think it's an impressive pen. I certainly like it, but I'm a big fan of big pens. And I love the lignum vitae with it. The finish is Pens Plus.
