OMG, these pens write so smoothly without skipping. The rubber grip is nice so the pen doesn't slip out of your hands. I have to say, the Blue Black ink color is by far my favorite!

I am sooo in love with the Blue Black ink!! The pen writes smoothly and it feels very comfortable holding the pen, not too skinny not too bulky. I love that the barrel tip is sort of oval shaped, letting the actual pen tip finish off the point (if that makes sense...) anyway, I highly recommend these :)

Beautiful smooth pen. Signo has done it again! This new version is light, elegant and the .5 ink is smooth and bold. I love taking notes with it.
