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: Lovely Pen by Uni - This pen is wonderful. Extremely fine line, 0.28, and the ink runs smoothly. It was slightly scratchy when i first used it, but it was also cold so i warmed up the pen between my palms for 30 seconds to get the ink flowing and its been fine. Even when writing at a quick pace. Im very happy so ive bought a 0.38 version too. Highly recommend this item.
Review: If Uni wants to send me a thousand of these.... please do!! :-) - I do not advise buying this pen... because all other pens will be ruined. It's a great quality pen with great writing - my notes are finally legible with the small nib. Doesn't take up more size than a regular pen. I'm currently on my second Uni Jetstream EDGE because I unfortunately lost my last one and it was like parting with my very soul. For such a low price too... Yeah, I bought another one as soon as I could.

### ⭐⭐⭐⭐⭐ Good pen and seller.
*by S***L on 11 October 2025*

I received a new pen in clean undamaged packaging. It was well packed and delivered promptly, so no complaints, a good seller. The pen itself is lovely, providing a dark and clean .28 line. However be aware that its feed does struggle to keep up when writing fast in cursive. However for note taking it’s fine.
