Perfection
My favorite pen! Flows smoothly, dries very quickly, minimal pressure to heavy pressure gives near identical line width, lightweight, easy texture to grasp. Pen perfection.

Finally, a good pen that I really like!
I actually first found out about this pen in a school meeting, we had to fill some paper work out and they let us borrow these pens, the moment I saw the pen and started using it I instantly just saw how great these pens were and I had to buy some for my self. These pens are great, they are very stylish on the outside and are made of recycled electronics! Writing with this pen is really smooth and I really love its micro point tip (0.5mm), which unlike other pens that are fine point like some Sharpy pens that I have used whose points get bent or damaged if you press to hard with them these pens are sturdy and super clean! They don't smudge the paper because the ink dries really quick and overall its simply a great pen that I highly recommend! From now on when I am out of pens, I will continue to buy these great pens! I rate these pens a perfect 5 out of 5 stars!I hope this review helped you out!Update: 2/11/13After having these pens for some more time I realized that some of the pens in the box are dry, not all of them just like 3 of them. Also I have noticed that the pens work great at a certain angle, otherwise the ink flow is not consistent and it doesn't write. I have lowered my rating to 4 stars, but these are sill nice pens overall.

Works and works well
These write so smoothly, as a result, your signature looks better than with regular ball points in my opinion. I have been buying these for years, and I haven't found anything that I would rather use.

Smooth writing
Got to know these because I borrowed a pen from someone. I had to buy them, the writing is so smooth and the way the ink works feels just right, weird that I've liked a pen so much lol
