Uni Jetstream EDGE 0.28mm Oil-based Ballpoint Pen, White Red Body (SXN100328W.15), Black

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!

Awesome pen. Wish it wasn't so on and off for specific surfaces

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.

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.

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!

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.
