There are lots of reviews of Lamy fountain pens, so I thought I'd do something different and mention the Lamy rollerball. I bought both at the recent Art Brown International Pen Shop Fair; the new purple black pens went fast, there were about 8 or 9 fountain pens when I stopped in the first day of the fair and bought my own fine point, and none on the second day when I went back for the rollerball.
This is a great pen, I'm liking it quite as much as the Tombow Object Rollerball. It's lightweight and the ink flows evenly, while the pen itself is a smooth writer. A real joy to use, although I'm so accustomed to a fountain pen that I keep thinking there is something wrong with this pen's "nib." It's a very nice, relatively inexpensive rollerball that will add some flair to meetings and to your writing.
