Uni-ball New Jetstream Extra Fine & ultra micro Point Retractable Roller Ball Pens,-rubber Grip Type -0.38mm-Black Ink-value Set of 10

One of my most favorite pens, works great, long lasting & super fine.

I and a pen snob and love a .38 - this is by far my favorite! Their colored pens are great, too!

Writes extra fine… great for writing in small spaces

This remains my favorite pen. It's 0.38mm but is a roller ball rather than a gel type pen so I don't have the same issues with smudging. This pen is highly recommended.

I cannot say enough how much I love these pens. In general, the Jetstream line of pens is great. The ink flows really smoothly, it doesn't smear or bleed through the page, and it doesn't seem to fade over time. Also, the tips on these pens are so fine! I would choose these over a micron pen any day, and that's saying something. They're great for art or writing. Kind of pricey, but totally worth it.

Ink dries fast and doesn’t smear.

They almost poke a hole in the paper you use them on…

Unreliable. The pen will write smoothly for a bit, and then the ink flow stops. Before starting again, the ink will pool on the page. Difficult to control, particularly for illustrations. Wouldn't recommend at this price.
