The Uni-Ball Jetstream ballpoint .7mm Pen is one of the very few ballpoint pens that I can honestly say that I like to write with.  In addition to enjoying writing with this pen, I also have to say that this is one of the more attractively designed pens that I have seen in a long time, excluding any pen that you might pay upwards of $25 for…luckily this awesome pen can be had from JetPens.com for only $2.25, and comes in red, black, and blue.  The thing I like most about the design of this pen is the fact that almost every inch of it is black excluding the plunger and the text on the side of the barrel.

When I first wrote with this pen I was very surprised by how smooth the ink flowed, and how effortlessly the pen glided across the paper.  I almost felt like if I didnt focus on controlling the movements of the pen on the paper, I would end up experiencing something similar to what happens when you hydroplane in a car.  It really was amazing to me that I was writing with a ballpoint pen.

It is hard to describe just how smooth a pen writes, but one thing you can see about this pen from the writing sample is the bright blue color of the ink, which is also surprising from a ballpoint pen.  Usually with blue ink in a ballpoint pen, the color is a bit more muted or dull, but this is not the case with the Uniball Jetstream ballpoint, the ink is a very bright and vibrant blue.  I have not tried the black or red ink in this pen, however I am pretty tempted to add those two colors of this pen to my next JetPens order (yes, because there is ALWAYS a next order to be had from JetPens) now that I have tried the blue.

If you take a close look at the ink cartridge of the Uni-ball Jetstream ballpoint(see photo) you will notice that there are some interesting differences between this pen and a regular ballpoint pen.  The first and most noticeable thing is that there is a translucent light blue collar that surrounds the bottom of the cartridge.  I couldnt tell if this was just to act as a spacer or if it somehow helps the ink to flow as smoothly as it does.  The second thing that you will notice when you look closer at the ink is that inside the cartridge, the ink seems to pinch together as you get closer to the tip.  Again, I was left to assume that this design somehow helps the ink to flow so smoothly.

All of this examining and wondering got me to thinking that I should probably ask one of my favorite Twitter users, UniBall_USA, aka Steve who is the Senior Brand Manager for Uni-Ball Pens.  As I mentioned in my previous post about getting to know people from the office supply world, Twitter is a great resource when you have questions like this. I reached out to Steve, and true to form, he was very helpful and told me to just email him over the questions that I had about this pen and he would get me answers.  Here is a summary of what I asked him, and his responses:

OSG: The first thing I noticed about this pen and all of the other Jetstream pens is the unique design printed on the clip. There are 3 open ovals stacked one atop another on the clip, do they have any meaning or significance?

Steve: The 3 ovals are a design element in many uni-ball products. They are on the clips of the Vision Elite, the Jetstream RT and many others. There is no real significance to the ovals or the fact that there are 3 of them it is a design element we utilize in our line of pens.

OSG: When I open up the pen and inspect the ink cartridge, I notice two interesting things towards the point of the pen that I have not seen in other Uniball pens. The first and most obvious thing is the larger light blue collar that surrounds the ink cartridge. I am wondering if this serves a specific purpose, or if it is just a spacer to keep the ink cartridge centered in the barrel of the pen? The second and more interesting thing I noticed was that about ¾” up from the point of the pen, the ink seems to be pinched together inside the cartridge, I assume that this is part of what helps to keep the pen writing as smoothly as it does, however any insight as to what exactly is going on in there would be very interesting to hear.

Steve: Without divulging any secrets both of those features are imperative to ensure the pen writes smoothly, doesn’t leak and operates skip-free.

OSG: Can you explain what it is about the design of the pen or technology behind the ink that makes it write so smoothly?

Steve: The ink is a modern marvel. It is a hybrid ink which is a mixture of Gel and Roller ink combining the super smooth features of a roller and the vivid color and lay down of a gel pen. The result of infusing these 2 inks together is the smoothest writing experience we offer with the added benefit of a quick drying ink that resists smearing.

OSG: Can you explain some of the differences between this ink and the ink used in a regular ballpoint pen?

Steve: A ballpoint pen’s ink is a paste-like consistency. To get the ink flowing in a ball point the ball needs to scrape the ink from the reservoir as it moves across the page. The Jetstream ink is a more fluid state that flows from the pen effortlessly as the ball begins to move.

OSG: The Jetstream has a significantly smoother feel when writing with it, what kind of testing was done with this pen in order to ensure that it provided such a smooth writing experience? I assume there was a focus on the amount of friction or drag created when moving the pen across a sheet of paper?

Steve: It is the smoothest pen we make providing the least resistance as it writes across the page. A funny side note, Uni-Ball in Japan has submitted the pen to the Guinness Book of World records for the worlds smoothest pen. Unfortunately, Guinness has not established a testing protocol for “smoothness” so they are unable to give us the title.

Uni-ball Jetstream ballpoint

The Uni-Ball Jetstream – An awesome looking pen. More importantly, an awesome WRITING pen.

I just wanted to put one more full unobstructed picture of the pen in here because I cant stress enough how much I really like the looks of this pen in addition to really enjoying writing with it.  I have to say, if you need to (or just want to) write with a ballpoint pen, this is the pen to get, the Jetstream is just the best ballpoint that I have ever written with, and it pretty much makes me want to toss every other ballpoint pen that I have on my desk because it will just be dissappointing if I ever have to use one of them again.

    I want some in blue. I keep looking in the stores and all I find are a multipack. This is a sport body, right? I like the standard barrel better but they are great pens. Nr

  2. 2

    Hey Nr, they list them on Jetpens as the “Basic Series” not sure about sport body, but I could see how that name fits with this pen.

    Great review! I love my Jetstream pens, I just purchased an F-series from Jetpens and its a good pen but I like the 1.0s that I purchased locally much better. I think the F series is a 0.5mm though, so maybe that’s why its not nearly as smooth and enjoyable as my other Jetstream pens which seem to glide effortlessly. I also bought my Dad the Black Alpha Gel series and that is one good looking pen, it is on the heavier side and has the Alpha Gel grip. Even the black metal body looks/is a brushed metal, very elegant and looks expensive. The Alpha Gel is also a 0.7 mm which is better than the 0.5mm in my opionion.
    Has yours cut out at all while writing? My Jetstream pens never seem to cut out, very nice indeed.

    This is the most magnificent pen in the world! At least in my opinion. I prefer the 0.5 tip and I find that it writes as smoothly as the 0.7. I use this pen exclusively for work and I do an enormous amount of writing on a daily basis. In this computer driven world, I work in an industry that still does most documentation by hand. I work in the nursing home sector of the health care industry and I literally write pages of notes per day. This pen has never let me down, never smudged and the smoothness ensures that my hand is not as tired at the end of the day!

    Some further thoughts on the Mitsubishi Pencil Company’s (I like that better then Uni-ball ;-)) Jetstream line.

    Based on Steve’s description of the ink, what exactly makes the Jetstream a ‘ballpoint pen’ then? There are gel ink pens that dry about as fast (or close enough) as the Jetstream’s ink.

    I too love the all-black look of the pen. The blue or red plungers on those models give a very nice small touch of color to them. This is about as attractive as an everyday pen can look. Though I would make some changes. I wish the three circles or ovals were diamonds instead. A more attractive shape in my eyes. I may be influenced in this by Franklin-Christoph’s now discontinued Model 59 ballpoint. A favorite all black fine pen that has a series of diamond patterns on its clip.

    Also, why does ‘0.7′ have to be at the top of the clip? Isn’t it enough to just have that on the package or on the removable UPC sticker on the barrel? I think the word ‘Jetstream’ once and the company name once or twice is more then enough writing on a pen. For those who agree with me on this, check out the ‘Color Body Series – White Body’ 0.7 Jetstream that JetPens sells. Not only does it not have ‘0.7′ but the three circles are missing, too. Only ‘Jetstream,’ ‘Uni’ and some small serial number are written on it. Perhaps some will find it too plain, but I think less is more when it comes to branding.

    For no particular reason, I’ll mention that I really like a lot of the stickers that one finds on most pens that JetPens sells. I tend to leave them on. I assume what is written on them is something very mundane to those in Japan or who know Japanese, but they offer a unique and exotic touch for those of us who don’t. Well, at least for me.

    One final thought on the Jetstream, it would be great if the model that OSG reviewed also had more ink colors to choose from for it. Or green, at least. The Jetstream multi-pens have green ink so they are making this unique ink in that color.

    I love the pen so much I have bought 10 of them and have stashed them everywhere–every room of my house, my car, my office, my purse-just so I don’t have to ever write with another pen. If that isn’t an endorsement, I don’t know what is!

    However–I am noticing that the pen starts to fail to write while there is still a generous amount (at least 50%) of ink left in the cartridge.

    Has anyone experienced this? I love the pen, but it appears that I am only getting 50% of what I am paying for. If I can’t resolve this, I may have to look into the Mitsubishi Pencil Company’s Jetstream as suggested by Der Bingle above.

    Der Bingle says:

    @Callie – I haven’t noticed the problem you described with any of my Jetstreams. Btw, Mitsubishi and Uni-ball are the same company.

  9. 9

    @Callie – I have not had that problem either, I know I’ve used up all the ink in a few Jetstreams with no issues.

    @Der Bingle – Thanks for chiming in, your feedback is always appreciated and helpful.

    Just a heads-up, I found a pack of 4 (2 blue, 2 red) for $2 at Big Lots today. YMMV but it’s worth going to see if you can find any, because that’s a great deal to be able to find 4 Jetstreams for the price of one! They’re the exact same as the ones in this review, retractable in full black with a .7mm tip. They also had a bunch of Visions and a few packs of Gelsticks.

    ThirdeYe says:

    By the way, does anyone else have an issue with using these on post-it notes? For some reason when I use these on post-its, they skip and leave entire letters blank at times. When writing on normal paper though, they’re a dream and one of my favorite pens right next to the Pentel EnerGel .5mm.

    nrepose says:

    I’ve noticed that this will happen with most pens if you write where the glue is. Does this happen on the entire pad or just on the top? Nr

  13. 13
    ThirdeYe says:

    nrepose – Unfortunately it tends to happen randomly throughout the entire note for me. I’m thinking there might be something wrong with that pen because the red .7mm I got in the same pack doesn’t exhibit the skipping issues on post-its that the blue one does.

  14. 14

    @Thirde Ye – That IS a great deal. Interesting that it now seems to be just the red that skips a bit on the post-its. Ive never had a problem, other than what nrepose mentioned about skipping where the sticky part is.

    @nrepose – Thanks for offering up the suggestions…good to see you around again!

    penlover says:

    @Der Bingle – The jetstream with a white body has fewer “marking” as you mentioned is because this model is marketed as a promotional pen allowing the name and/or logo of a company to be printed on the it. The same goes for why the three ovals are missing. If you go to Mitsubishi pen’s Japan site and check out their catalogue than you’ll see it. You may also note that the white body is not available in retail stores with the exception Jetpens.

    Der Bingle says:

    @penlover – Thank you for the information. I appreciate it.

    where can i buy this pen…. are they out in the market…..

  18. 18

    @sandeep – Right now it looks like JetPens is out of stock, but also it looks like Uniball has slightly updated the look, eliminating the all black, and adding some more white and color accents to them. The all black one now has a clear plunger, but looks like the rest is the same.
