Featuring a revolutionary 0.28mm ball tip and quick-drying Jetstream ink, it delivers ultra-thin, clear lines with minimal smudging. Its stylish white-red brass body offers ergonomic stability, making it ideal for detailed writing and fine print. This refillable pen is a niche luxury tool designed for those who appreciate the art of writing with finesse and are willing to master its unique angle-dependent flow. ## 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: NOT a run-of-the-mill pen - Read before you buy - Its not a regular ball pen and you will surely be disappointed if you buy it expecting the performance of a regular pen. About me - I invest in stationery and buy unique products. I like the experience of getting new (& less known) pens and trying them out. About Uniball - Uniball is the world leader is pens and you may have used pens by this company. If not, please buy them and try - they are a delight to write with. About this pen - its a niche product with very fine tip (0.28 mm). Therefore the USP of this pen is its fine writing. And that's what you should buy it for. The weight is well distributed, the bottom being heavier that the top. And its very comfortable to hold. Pros Writers very smooth, like butter. The fine tip is a delight for those looking for a unique writing experience. Uniball quality shines through - as I said, they are world leaders in pens Cons The pen writes best at a particular angle; so you have to adjust accordingly. Like many ball pens, it takes a day or two to catch up and become smooth. Before that, you require patience. After that, its a joy to write! Since its a niche product, refill availability will be a problem. I plan to buy some from desertcart and stock up. Price is high - but its a niche product, not your regular 10-rupaye-wala-ball-pen-available-at-nukkad-shop. So if you know what you are getting into, buy it, give it a few days and enjoy the ride! Imagine the pen being an orchid - requires care and watering and will wither away in harsh conditions; but when it blooms, its a joy to watch! Hope the review will help make you an informed purchase decision. This pen is not for everyone! Review: The pen is not for everyone - There are many factors which this pen requires. Many people have the audacity to write horrible things about a pen which is strictly for fine pen writers. And this pen requires you to have an active interest in fine pens or else you just won’t find it as appealing to hear as when you actually buy it. Now for the factors: 1) This pen strictly requires an angle to write perfectly, any other angle will make the ink come in an uneven amount. 2) The ink is slow to finish but it requires 1,700 to buy a new ink so only use this pen on special occasions. 3) This pen is sensitive, if you exert too much pressure, it will bend/break. So be gentle. 4) If the pen doesn’t work on the first try, don’t give up, it just means the ink is dry or your angle is incorrect. That’s all thanks for looking at my review ## Features - Import from Japan ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B082ZXNTRL | | Age Range (Description) | Adult | | Age Range Description | Adult | | Best Sellers Rank | #18,522 in Office Products ( See Top 100 in Office Products ) #845 in Stick Ballpoint Pens | | Body Shape | Round | | Brand | uni | | Brand Name | uni | | Closure Type | push bottom | | Colour | White Red | | Customer Reviews | 4.1 out of 5 stars 2,094 Reviews | | Drill Point | Fine | | Grip Type | Contoured | | Hand Orientation | Right | | Hardness | 2H | | Included Components | Ink Cartridge | | Ink Base | Oil | | Ink Colour | White | | Item Diameter | 11 Millimetres | | Item Dimensions | 12 x 11 x 143 Millimeters | | Item Type | Stick Ballpoint Pens | | Item Weight | 13 g | | Line Size | 0.28mm Millimeters | | Manufacturer | Uni | | Material | ‎brass | | Material Type | ‎brass | | Model Name | Gel Pen | | Model number | SXN100328W.15 | | Pattern | printed | | Recommended Uses For Product | Writing | | Special Features | Refillable | | Style Name | Minimalist | | Subject Character | Ballpoint | | Unit Count | 1 Count | | Writing Instrument Form | Ballpoint Pen | | Writing instrument form | Ballpoint Pen | ## Product Details - **Brand:** 三菱鉛筆 - **Writing instrument form:** Ballpoint Pen - **Colour:** White Red - **Ink Colour:** White - **Age Range (Description):** Adult ## Images ![Jetstream EDGE 0.28mm Oil-based Ballpoint Pen, White Red Body (SXN100328W.15) - Image 1](https://m.media-amazon.com/images/I/61-8WDA9EVL.jpg) ![Jetstream EDGE 0.28mm Oil-based Ballpoint Pen, White Red Body (SXN100328W.15) - Image 2](https://m.media-amazon.com/images/I/61f7rru4HEL.jpg) ![Jetstream EDGE 0.28mm Oil-based Ballpoint Pen, White Red Body (SXN100328W.15) - Image 3](https://m.media-amazon.com/images/I/81A3ovmNV+L.jpg) ![Jetstream EDGE 0.28mm Oil-based Ballpoint Pen, White Red Body (SXN100328W.15) - Image 4](https://m.media-amazon.com/images/I/81IjJaZ-JRL.jpg) ![Jetstream EDGE 0.28mm Oil-based Ballpoint Pen, White Red Body (SXN100328W.15) - Image 5](https://m.media-amazon.com/images/I/81BJjkLA8gL.jpg) ## 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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ NOT a run-of-the-mill pen - Read before you buy *by D***� on 28 December 2025* Its not a regular ball pen and you will surely be disappointed if you buy it expecting the performance of a regular pen.
