Uni Jetstream EDGE 0.28mm Oil-based Ballpoint Pen, Navy Body (SXN100328.9)

I bought one of these after seeing it mentioned on a pen review site. I've been a happy user of Uni's Jetstream pens for years and was intrigued by the idea of trying a fine-point version. Since getting my hands on it I've been using it quite a bit and I can say that for my own usage, it's not going to replace my Jetstreams. The fine point tip makes lovely precise lines, but it just doesn't flow as smoothly as the larger pen tip. If you're looking for a fine point pen for precise detail work and are a fan of Uni's rollerball pens then you will assuredly like the edge. The physical styling of the pen is somewhat dramatic compared to others I've used. I imagine this could be a divisive point. I like how it looks and feels, but it may not be to everyone's taste.

This is easily my favorite pen. I love a good ultra fine point, and this is the finest point I’ve found. It writes smoothly, without skipping. The pen has a nice weight to it. It’s the pen I reach for the most often, by far. I do wish it came with different color ink options- like a dark navy or gray- but otherwise it’s pretty perfect for me.

Love the heavy weight of this pen. The tip is extremely thin, my only gripe it’s almost too thin and can fill a little sticky if you write too hard as it is sharp to catch the paper. I love the navy blue color and there is also a mint color. Feels comfortable while writing. And because of the weight it feels more durable just have to change ink.

Here I am reviewing a pen on Amazon. The places COVID quarantine life takes you. Pen feels robust and is nice to look at. Obviously a 'homage' to the Rotring, but of lighter material and not balanced. It is bottom heavy and the design makes it so that I've already repeatedly mistaken the top for bottom and bottom for top when I go to pick it up. The click mechanism has a cheap plastic rattle and the plunger wobbles. Man I am really nitpicking. It is an oil-based ballpoint pen and depending heavily on the paper it writes beautifully putting down full-bodied creamy lines. It works wonderfully in my MoleSkine Cahier notebooks, but fails shamelessly on some other papers. Compared to my gel ink Signo 0.28 pen, this pen is a lot more paper-selective. That said, this pen excels on more surface-porous papers (if that's the right description) where the Signo gel ink would start bleeding with slower strokes. The grip / barrel is smooth and while being bottom heavy helps, it requires more force to grip and my weak little hands are more prone to cramping when using this pen to write or draw for ants--as one does with 0.28 pens. For a roughly $12 pen, it is slightly disappointing in it's difficulty to hold and use, the tiny refill, and its selectivity when it comes to papers. But it looks amazing, the finish on mine is flawless, and on the right paper it writes quite nicely--also, the 0.28 tip is a treat for those looking for fine pens for detail sketches or small notes. I'd buy again, despite complaining about it for several paragraphs.

Just what I need sharp lines and smooth

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).

This pen writes very smoothly, considering that the tip is almost like a needle. The ink is oil-based so it doesn't run. It's well balanced and doesn't need a pen pillow on it. What's not apparent until you get it is that barrel is not round. That's not a deal breaker, just something I think I should point out. Edit: Drawback is that the description isn't clear that this pen contains black ink. HOWEVER, the ink color isn't made clear. I have an irrational hatred of black ink, so I will have to buy blue ink refills. I am not sending it back, though. It writes too well for that.

I would give the Uni Jetstream .28 oil-based pen 3 stars. It is definitely a well-made pen, and the ink flow is smooth, clean, and reliable. For writing and crisp line work, it performs very well, and I can understand why many people like it. That said, I was a little disappointed with how difficult it is to make light marks. I was hoping it would work better for delicate sketching, soft lines, and light cross-hatching, but the marks tend to come out darker and more consistent than I wanted. It doesn’t give me quite the range of pressure control I was hoping for as an artist. It is still a great pen overall, especially for writing, notes, and clean detail work. I just don’t think it is the best choice if you are looking for subtle value changes, light hatching, or a more delicate drawing feel. Good pen, just not perfect for what I wanted it for.

The pen is well built and writes smooth even with a tiny tip. So it does what it promises. However the oil based ink is too weak for my taste. Wouldn't be my daily pen.

When it works, it's really interesting having a tiny ball... but the ink doesn't flow properly for long. It lasted 2 weeks and then is only working on and off. :( Concept is interesting, though

This pen has become my new favourite for everyday notes. The tip is incredibly precise without feeling scratchy, and the ink flows really smoothly. The navy body looks smart and feels great to hold. If you like clean, fine lines and a pen that just works every time you pick it up, this is a brilliant choice. The only issue I'd say would be the way it sits in my hand specifically leaves a mark on my finger after intensive usage.

I already have good pens for daily writing like the Zebra Sarasa and the Uni Jetstream 4&1 Metal body, and I don't write in 0.28 very usually. This pen is like a cool trinket for use in very niche conditions, and I mainly got it for the body and the novelty. I like the body, I used it with the 0.7 jetstream multipen refill and its wonderful, but I still prefer Zebra sarasa. 0.28mm is also very thin and isn't very smooth, as expected. Only get this pen if you have an already large collection of pens and pencils. I do, and I like this pen. Do mind that the ink was skipping so i got the whole pen refunded.

Excelente viscosidad y la finura de la punta me encanta
