I said to the well due to the reviews Lamy rollerball swift Matt Black Model 331 and the good price-performance ratio, especially since I had lost another rollerball the brand Lamy. Since I am a bowl many times, I did not want to invest vast sums in return a rollerball pen also. For signatures, etc. I would always prefer a rollerball for the sophisticated typeface a ballpoint pen. An alternative would be a fountain pen. However, these mostly dry a slightly while rollerball is always functional, unless the mine is coming to an end.
