## Overview

The uni Jetstream EDGE 0.28mm Oil-based Ballpoint pen refills (SXR-203-28 Blue) deliver ultra-fine, smooth writing with fast-drying, low-viscosity ink imported from Japan. Designed exclusively for the Jetstream Edge series, these refills feature the world’s smallest 0.28mm oil-based ballpoint tip, ensuring crisp, clear blue lines with minimal friction. The set includes five refills, each engineered with a sleek point chip for precision and durability, making it ideal for professionals who demand flawless fine writing.

## Description

≪Product features≫ A ballpoint pen replacement core exclusively for the Jetstream Edge series. With ultra-low friction "Jet Stream Ink", you can write unprecedented fine characters with an ultra-fine ball diameter of 0.28 mm. The world's first oil-based ballpoint pen category, the world's smallest, ultra-fine ball diameter of 0.28 mm *. Compared to our gel ink ballpoint pen with the same ball diameter, the line width is narrower. Since it uses "Jet Stream Ink", which is a low-viscosity oil-based ink, it dries quickly and allows you to write dark and clear lines smoothly. Newly developed "point chip" with easy-to-read writing surface The newly developed "Point Tip" has a slim shape that is squeezed toward the pen tip so that the pen tip looks clear even when doing fine writing work.

Review: Great ink! - Love these extra fine refills! No issues with the ink not flowing like I've had with other fine tip pens.
Review: Skippy - A refill takes me about 9 months to go through completely. This is my second refill and it skips like crazy. I can tell there is some kind of defect, as it scratches the page whenever it is not placing ink onto it. I can actually feel the defect in the ballpoint. When a refill works, it writes fairly smooth without any issues on most paper (with some notepad paper exceptions). I would rate that a 5 star performance. However, I'm already experiencing defects with just the second refill. That's a 50% failure rate. That is disappointing. I wish I knew how to troubleshoot it in order to get the ink to flow the way it is supposed to. I don't know whether I would buy it or not at this point. I don't recommend it. If you're looking for a very fine line that writes without skipping 100% of the time, look elsewhere.

### ⭐⭐⭐⭐⭐ Great ink!
*by B***R on December 10, 2025*

Love these extra fine refills! No issues with the ink not flowing like I've had with other fine tip pens.

### ⭐⭐⭐⭐⭐ Wonderful!
*by B***O on July 29, 2024*

This pen is the bomb. I use it for Journaling. It writes so smooth. Just one hang up, the cartridges don't last very long. I had some refill cartridges but I moved and have yet to finding them. So I needed to order more. Because I can't live without this pen. You should order it and see for yourself!
