## Overview

The Uni Jetstream EDGE 0.28mm oil-based ballpoint pen from Japan redefines fine writing with the world’s smallest ball diameter in its category. Featuring low-viscosity Jetstream ink for ultra-smooth, quick-drying lines, this pen combines precision, durability, and a sleek ergonomic design. Ideal for professionals who demand clarity and control in every stroke.

## Description

The Jetstream EDGE, with the world's smallest ball diameter of 0. 28mm, has been newly added to the popular Uni Jetstream series, which is popular for its smooth writing and quick drying. In recent years, the need for fine print of oil-based ballpoint pens has increased, and Uni has begun planning and developing an ultra-fine ball diameter of 0. 28 mm. The world's first ultra-fine ball diameter in the oil-based ballpoint pen category, 0. 28mm. The drawing line width is thinnner than our gel ink ballpoint pen with the same ball diameter. Uses low-viscosity oil-based ink, "Jetstream Ink", so it has excellent quick-drying properties and can write thick, clear lines smoothly. The body axis is designed to express the thin and sharp image of the 0. 28mm ball diameter drawing line in a stylish manner, and also focus on functional aspects such as stability during writing. As a specialized tool for writing fine print, we focused on the material, design, and usability of each part.

Review: Ultra-Smooth Precision Writing - The Uni Jetstream EDGE 0.28mm pen delivers exceptionally smooth ink flow with sharp, precise lines. Stylish design, comfortable grip, and reliable performance make it perfect for detailed writing and everyday use.
Review: An awesome pen and new regular! - 5 stars to the seller, to those in delivery, and to the Uni Jetstream edge pen! I love the .28 nib! I am excited about this pen on every facet! It’s smooth fine line, feel of the road. It is like an expensive sports car ride. You will always get a smoother write, most of the time from a 1.0. I consider 1.0’s like the smooth ride of a big Cadillac or Lincoln. This pen’s feel and 0.28 mm nib offer a smooth write with also the light feel of the road that adds better control for a better legible write. A most excellent pen. You will always see me carrying this and the Signo 0.28 in my pocket! The ones to beat, in my opinion. I cannot wait to try out the Edge 3 which offers multi colors - a pen I use much in the field of my work!

## Questions & Answers

**Q: Does this pen turn the side of the left hand black when a left handed writer uses it?**
A: I am left handed and love it.  I write normally and not with my arm bent like some left handed people do!

**Q: will this write on transparent sticky notes?**
A: I did not have a transparent note to test this pen on but I did try a sticky shipping label and it wrote on that but it did need a second to dry without smearing. I also tried a sticky tab I use for making notes in a book and the results were not very good

**Q: Will this ink bleed/run if water drips onto the page?**
A: I had some notes written on a notepad and some condensation from water bottle dropped and ink did not run or spread

**Q: will this pen take other uni refills if I prefer 0.38mm for instance?**
A: No.   However Uni did make a 0.38 version of this pen in Japan and those refills should be more widely available soon.  The 0.38 version only recently came out with different color schemes

### ⭐⭐⭐⭐⭐ Awesome Writing/Drafting Instrument
*by A***N on May 27, 2021*

Like all Uni products, the quality, look and feel are excellent. In my case I keep a journal daily using the 'Eisenhower' layout with a few boxes added showing my daily sales numbers vs. goal. Using a small paper thin ruler that fits the journal's pocket, the edge was not friendly to various gel pens I tried using. The Fisher Astronaut pen holds up well in this regard, but designed more for writing and doing continuous lines, leaves some annoying artifacts. The Jetstream .28mm is really superior - I can use the side of the point right against the ruler edge with no worries of damage to the pen, as I do my Rotring 600 mechanical pencil. The oil ink has a perfect flow. Not forgiving if I make my own error, but as long as I do my part, the reward is bold but spiderweb-thin lines with no streaks, clots or any other sloppiness. Completely worth the price without going into professional grade drafting instruments!
