I seldom feel so compelled to write fan mail about something as simple as a pen, but in the case of the Signo-White Uni-ball Impact Pen, I had to write. This pen is amazing. The ink flows smoothly, it writes with no skips. It is truly remarkable. I use the Signo black pens all the time just for writing, never knowing that the white pens even existed. I must confess, I bought 3 of them. Could be why the stock is down to two as of a few minutes ago. Grab these pans up ladies, they are a miraculous discovery!!!
