## Description

Uni-ball New Jetstream Extra Fine & ultra micro Point Retractable Roller Ball Pens,-rubber Grip Type -0.38mm-blue Ink-value Set of 5

Review: Smooth Operator - As usual Uniball quality shines through on these little gems. I prefer a fibe tip pen however some tend to be draggy as you write. These are as smooth as .7 and lay down a consistent line of ink. Being left handed pens are important as well the quality. If you need a fine line pen I would recommend these. As far as the supplier I have made several purchases through them on desertcart and everything is always as advertised and in perfect condition upon arrival.
Review: Love these pens! - Love the fine point, makes my handwriting look amazing. Ink flows well, but can be a little scratchy at times, which doesn't bother me. Ink smears with highlighter if you highlight immediately after you write. I did drop a pen, which messed up the ballpoint. The pen would skip when writing and I had to throw the pen out. Overall, best value for a quality pen.

### ⭐⭐⭐⭐ A little bit too fine
*by S***R on June 30, 2022*

After using these for a couple of years, I see that I use them less than I initially thought I would for just one reason: the line deposited is a little too faint. Its simply not dark enough, and the reason is because its a very very fine line, especially for a ballpoint pen. This leads to me pressing down harder, thinking it will change the line darkness, but it does not. It only ends up putting strain on my hands and leaves me with a scratchy experience. Other than that bit of preference on my part, this pen is from the Jetstream line, and it is extremely well made, comfortable, and smooth to use, just like the other pens in the line. Another thing: one pen was writing really really faint, and I had it lying on a table by the front door. When I was looking for scissors or a pocketknife to open a package, I couldn't find one nearby, so I grabbed the pen, and quite easily stabbed the tape that was on the package. I chuckled at the fact that it was so well made that it survived that with no issues. It's actually a little dangerously fine, to be honest.
