Review: This pen will improve your handwriting and make you look better - It will improve your hand writing. This pen roll smoother than other pens. The ink dries quickly so no smudges. Everyone who has borrowed my pens ove the years have been impressed. More than five years ago I did a search on the top ballpoint pens. This was on the list as one of the best. I agree, I purchased three or four of the top performers and this was the leader. A really good combo is a quality notebook like moleskin.
Review: This is the BEST pen in the world (especially for lefties) LOVE it. - I'm left handed, and I found this in a left handed store. It's not that it is only for lefties, but it has exceptional features -- that even lefties can rave about. We lefties push our pen rather than pull it along and so our hand goes right over what we've written, resulting in ink coming off the paper onto our hand. So get this: 1) it glides like a charm. The uniball dispenses the ink easily, evenly and smoothly. 2) the ink dries immediately, so no smudging onto the hand! 3) it's comfortable to hold and is padded for long use. I have given these pens as gifts to righties and they also love them. One friend says "it is the best pen I've ever used." Seems weird to be so enthusiastic about a simple item as a pen, but it's an essential tool, right? So nice that something so ordinary as a pen can be such a pleasure to use! I have many all over the house, it's the only pen I want to ever use. Finally, a well-designed, superb functioning pen that is reasonably priced!

### ⭐⭐⭐⭐⭐ The best pen, the best ink, the best feel
*by J***S on August 25, 2013*

I have, for many years, searched for a pen I could use all day. No, really. I took paper and pen notes in college, and used mediocre pens. I took paper and pen notes in grad school, and used a reasonable pen (some inhouse type from Staples). One wonderful day (yes, I am dead serious, a wonderful day; keep reading) I got an offer from Uniball: free pen. I received a red Jetstream RT. I immediately began seeking out black ones. What I love about these pens: the solvent used to make the pen glide means VERY little pressure is needed as you write, so you can easily write a lot and for long periods of time without the soreness that comes from pressing down with a cheap pen all day. The grip itself is quite comfortable, and the pen is large enough that those with any size hand should be happy with it. The ink is remarkable. It shares a few things in common with permanent marker ink, so it will not wash out; these are great for signing checks for that reason, and of course if you spill something on what you've written there will be a little yellow bleeding, but the original marks will still be as clear as day. Additionally, the ink dries RIDICULOUSLY fast (that same great solvent) so even LEFTIES will be pleased. Finally, and among my favorite features, the ink does NOT bleed through the page while you're writing. If you're feeling particularly green, you can buy ink refills on Amazon and most office supply places for these pens. Unplanned feature: the pens will actually survive a clothes washing incident WITHOUT leaking all over your garments. The pen will likely be kaput, but to have no ink marks on clothing is a really great thing. This has happened twice. I literally took paper notes through the entirety of law school, and this was the pen I used for 90% of that time. They are often sold in 3 packs of a single color or the office combo (red, blue, and black). Look around on Amazon for the 12 packs of these pens if you fall in love the way I did. I came to find that for taking notes in law school (and again, I used these almost since day 1), I preferred the 1.0 mm Jetstream RTs. For exams (including a bar exam), I used the 0.7mm Jetstream RTs. I hope this helps someone. I really cannot oversell these pens or overstate how pleased I continue to be with them. Edit: Used a Jetstream RT to take the MA bar exam. Passed. Was as comfortable as I could be with such smooth-writing instruments all day long.
