## Overview

The Uni Jetstream EDGE 0.28mm is the world’s first ultra-fine oil-based ballpoint pen, featuring a precision 0.28mm tip and quick-drying low-viscosity Jetstream ink. Designed with a sleek navy body and metal grip, it offers smooth, smudge-free writing ideal for professionals who demand clarity and style. Refillable and lightweight, it’s engineered for durability and comfort during detailed note-taking or fine print tasks.

## 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.

### ⭐⭐⭐⭐⭐ It is very durable.
*by H***R on July 31, 2025*

This is a great pen if you like super fun point. It has the perfect friction against all paper types. I can’t say enough good things about it. It works great for notetaking in the margins in a Bible or textbook.

### ⭐⭐⭐⭐⭐ Love this pen
*by L***S on May 13, 2025*

Love this pen. Writes smooth, very light, feels great in the hand.

### ⭐⭐⭐⭐⭐ Fine Line Writing
*by A***R on February 2, 2026*

I like writing instruments, pencils and pens, that write a fine line. One of my co-workers was using one and I wanted to try one myself. I have been using it on a regular basis since receiving it. The fine line it produces is just what I wanted whether I am writing or drawing. I have to hold the pen more vertical to obtain the best line and sometimes it takes a stroke or two after a long pause in use to get a good line (may also be the condition/type of paper).
