Review: Very smooth! - These pens write so smooth! The only thing I don't care for is the ink flow. As long as the tip of the pen is touching the paper, that ink FLOWS. It can leave little pools of ink on the paper. Knowing this, I don't use them for doodling or drawing. They are strictly for taking notes or for work. These pens are lightweight and feel good in the hand. I really enjoy the different colored barrels. Japan makes the best office supplies.
Review: Favorite pen - Smooth ink flow, comfortable to write with.
