## Overview

The Uni Jetstream EDGE 0.28mm is the world's first ultra-fine oil-based ballpoint pen, engineered in Japan for precision and smoothness. Featuring quick-drying Jetstream ink and a stylish, ergonomic design, it delivers crisp, smudge-free lines ideal for professionals who value clarity and speed in their writing tools.

## 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.

## 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

### ⭐⭐⭐⭐⭐ Buy one
*by A***M on 8 June 2026*

Fantastic pen, great ink flow, easy to hold and beautiful design

### ⭐⭐⭐⭐⭐ Smooth!
*by B***D on 21 July 2026*

Very smooth flowing ink for such a fine point pen. More ink colours please!

### ⭐⭐⭐⭐ Crisp skip-free fine lines
*by T***D on 16 November 2025*

Good construction, writes a crisp fine line without skipping. Very slightly scratchy writing experience but this is typical for such small nib sizes. Very good for technical drawing or fine shading
