5 stars to the seller, to those in delivery, and to the Uni Jetstream edge pen! I love the .28 nib! I am excited about this pen on every facet! It’s smooth fine line, feel of the road. It is like an expensive sports car ride. You will always get a smoother write, most of the time from a 1.0. I consider 1.0’s like the smooth ride of a big Cadillac or Lincoln. This pen’s feel and 0.28 mm nib offer a smooth write with also the light feel of the road that adds better control for a better legible write. A most excellent pen. You will always see me carrying this and the Signo 0.28 in my pocket! The ones to beat, in my opinion. I cannot wait to try out the Edge 3 which offers multi colors - a pen I use much in the field of my work!

Like all Uni products, the quality, look and feel are excellent. In my case I keep a journal daily using the 'Eisenhower' layout with a few boxes added showing my daily sales numbers vs. goal. Using a small paper thin ruler that fits the journal's pocket, the edge was not friendly to various gel pens I tried using. The Fisher Astronaut pen holds up well in this regard, but designed more for writing and doing continuous lines, leaves some annoying artifacts. The Jetstream .28mm is really superior - I can use the side of the point right against the ruler edge with no worries of damage to the pen, as I do my Rotring 600 mechanical pencil. The oil ink has a perfect flow. Not forgiving if I make my own error, but as long as I do my part, the reward is bold but spiderweb-thin lines with no streaks, clots or any other sloppiness. Completely worth the price without going into professional grade drafting instruments!

The pen feels great, quality wise. It’s amazing that they can get a ballpoint pen on 0.28mm. The ink is nice and it doesn’t smear easily. I also haven’t had any bleed through issues. I do wish it wrote a bit smoother it has a bit of a scratchy feel but that is somewhat expected with the finer tipped pens. Overall it’s a sleek pen and I enjoy using it.

Literally my favorite pen, if you like a thin tip that flows smoothly, this is the best. The 0.28 mm tip pen from muji always stops working for me after awhile even before using all the ink, I think the tip gets clogged or something but that has never happened with this pen. Highly recommend for 0.28 mm tip pen lovers!

It's a very very small ball, so of course it will have a bit of trouble writing. The line is very thin, and it's a dense, good quality plastic design. Ink had trouble from the beginning but it smoothed out for a while. It then dried out a couple weeks after opening because I didn't use it much I imagine. Not very comfortable to hold. I got it as a "wow look they make one smaller than .5!" novelty and had my fun. Wouldn't use this for daily writing, if you want something thin I recommend a Japanese made extra-fine nib fountain pen, which gets down to about .3 without the ink ball trouble. Plus the refills are easier and wider variety of color.

I really like these pens. They write very cleanly and last for quite a while. No issues with bleeding or excessive ink and I love the different pen body color options while sticking to black ink.

I have a great appreciation for fine tip pens, the smallest diameter being 0,38 mm Uni which I absolutely depend on for daily writing. After I saw this pen in a youtube short about some of the best new Japanese Stationary products I was persuaded to purchase this pen by its unique features, particularly the thin tip which allows users to see more of the area they're writing and the ergonomics of the pen, it's nicely balanced and the wire clip is very cool. What absolutely sold me however, was the advertised "world's diameter ballpoint pen" at 0,28mm. When this pen arrived it wrote great, smooth as any Uni pen I've used and produced a fine thin line. This lasted for several minutes before the pen started to fail. I attempted to correct the failure by scribbling circles, checking the ink cartridge, and cleaning the tip. The pen continued to fail. I returned the pen and was sent a replacement however the results were identical. I'm highly disappointed. To be perfectly honest its been years since I used a pen that didn't work minutes after unpacking, and has never happened to me with a Uni product.

Salve, stupenda penna , scrive sottilissimo e non sbava mai

Best pen I ever had... and I had lots, as a stationary fanatic

0.38 mm nib of my dreams. Ink flow is smooth and consistent, no thick splodgy scrawls. Excellent for my cursive penmanship, which can be as illegible as a gerbils dirty scratchings to both others and myself when using anything larger than 0.25mm. Vision loss no longer need be a risk when having to decipher my handwriting. Never thought I’d write clearly again after Muji discontinued their extra fine tip. Hooray. Thank you Uniball.

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 Amazon 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!

This is not for everyone but if you appreciate hair thin lines then you will freaking love this pen. I received it and have barely let it out of my sight since. I love love love the super fine line of the .28. I tend to write with my pen in a more upright position — more like a sumi brush than a ballpoint — so for me this pen works very well. If you tend to hold your pens at a more acute angle to the page you may find it a bit skippy. 100% would buy again — new fav pen for sure.
