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

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!

I recently started using the Uni Jetstream 0.28mm. I’m thoroughly impressed! The fine tip allows for precise lines and clear lettering even with my messy handwriting. The pen gives clean lines ideal for detailed writing and note-taking. The ink flows smoothly without skipping, and as a left-handed writer, I appreciate how quickly it dries, preventing smudges.

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!

The pens are great. They have a solid build and weight but my issue must be on a consumer side. The 0.28 width absolutely slices through paper. I buy pretty good quality thick paper and these pens felt like writing with a box cutter. I had to change my writing style to not be so heavy handed. That’s on me, I’ll get something thicker to suit my pressure.

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.

IMHO, this is 3.5 out of 5, so I've rounded off to 3.The best part of this pen is the metal front section. It's a nice matte metallic finish with groups of etched lines and a nice bit of heft. It's a stark contrast to the rest of the pen, though.You'd think this takes a nice sized refill. Sorry, but it's more like a D1. Yes, you have all of that body space yet only a D1 style refill inside. Ridiculous! The only plus to this included Jetstream refill is that it's a very nice precision tip, has reasonably good ink, and the reservoir is clear to the fill level is easy to see (unlike with metal D1's). But it's also fragile and requires a light hand. Pressing too hard can cause some blobbing and skipping (paper fiber being scooped up).The barrel is made of a glossy lightweight plastic, the kind that you find on disposable free ballpoint pens you get at businesses, doctor's offices, events, etc. The clip is an artful design and it glides onto fabric fairly easily... but it shapes it into a curve, as opposed to just a flat compress, which means you may get visual impressions left behind on clothes. Lastly, the rear clicker is this boring thin matte black piece of plastic.At least the click action is good. And on my example there isn't any bothersome tip wobble. The refill is press-fit into a tubular dock inside the pen that holds on very well. When you pull on it to extract, you can feel nice resistance.Upshot? Half-baked. Starting with the front, Uni had a nice pen going on... then after it hit the body, the rest just sank. I got it for the looks, and the looks is about all I got. Maybe later, Uni will revisit the EDGE and include a more premium main barrel, as well as rig it to accept larger refills.

OMG I love this pen. I thought it was a mechanical pencil at first but it works for me as an architect to get little finite print on drawings or documents!

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.
