The Uniball Sino RT 0.38 Millimeter Pen

The 0.7 millimeter was the best size for me because that's why I've been used to. Sure. And I felt that anything below that would just be like cutting holes in paper. One day I walked into a office max and saw a 0.38 millimeter pen, a uniball sino RT, 0.38. Almost all the main pin manufacturers now have a sub 0.5 millimeter pin available on an office plus store shelves. It's starting to become more prevalent list these days.
