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

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. Writes smooth, very light, feels great in the hand.

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.

It is a comfortable pen to write with and the clicking function is extremely smooth. It is the best ultra fine pen I've used, but I think that 0.28 is too sharp for the paper I have to use at work. Additionally, I am knocking it down a star because the ink will skip around at times, making me have to go back over what I wrote.

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.

Writes smoothly. Feels great in the hand. Ink dries very quickly and doesn't smear when you rub your hand or object after you write. The quality and durability will make this pen useable for years

Feela fairly solid while still being light. Writes very well for how small it is however if your heavy handed or using lower quality paper it does catch the paper more often. The grip on it is also very slick but with how light it is that isn't as much of a problem.

This pen literally does not work and I will never understand how it made it past quality control. I purchased this after seeing it on a YouTube video that talked about unique writing pens. I am always looking for pens with very fine nibs, and at 0.28 mm, this definitely qualifies. But it also qualifies as unique in that it has one feature no other pen does: it doesn't write. The ink constantly stops flowing no matter what paper type you use or at what angle you hold the pen. In the attached video demonstration, I write in a nice leather bound journal as a test. No one wants to watch a five minute video where I write the same thing on a bunch of different types of paper, but if you're willing to take my word for it, the results are exactly the same as you see here no matter what type of paper I write on. This is going back for a refund. How did this ever make it out of the factory?

la punta es extra fina, con tinta de color azul pálido, cuerpo ligero de plástico extruido

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.

細いけどしっかり滑らかに書ける。 グリップ部分の金属感も触っていて気持ちいい

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.
