Uni Signo DX 0.38mm Review


The pen that started it all. One of my first pens from JetPens. The most prominent one I can remember. I’ve been fastidiously using this pen for going on 2 years now. To this day, I just can’t imagine a better pen. I’ve been searching around for a while, but I end up coming back to this one every single time. So let’s dive in and see why this is one of the most perfect pens for me.


Predictable, right? If I had a quarter for all the time I spent brainstorming and typing up a rant about grips, I’d be a couple million dollars richer. All jokes aside, I hold the Uni Signo DX’s grip as my gold standard in utility and comfort. It seems that Uni really hit the nail on the head when it comes to pattern and thickness. The rubber is thick enough to provide a decent amount of cushion, while at the same time keeping in line with the pen’s slim form. The pattern is a rather simple linear group of dual columns wrap their way around the grip, leaving a few spots with just plain rubber. This grip is the most effective in function that I’ve ever had the pleasure of using. Well played Uni, well played.


I had a certain hesitation when it came to using this pen at first. It was my first foray into micro tip gel pens, having used mechanical pencils for the longest time. I used to be that kid who still used 0.7mm pencil when everyone else used 0.5mm. I had no choice but to keep track of my lead supply, otherwise I was out of luck in finding anyone who can spare some. The fact that I would be using a pen for schoolwork that would be graded just didn’t feel right, I felt that there were so many things that could go wrong, but I decided that just trying it out for a couple weeks wouldn’t be too hard. I started using the DX the moment I unwrapped it from the copious amount of bubble wrap that it was encased in. After a few sentences, I felt a lot better about the prospect of writing with it. The in flow was smooth and consistent, almost negating the small amount of feedback I felt when using it. All my lines were crisp and clean, perfect for my writing style at the time, a hybrid of block and cursive. As the months went by, it wasn’t until the pen ran out 4 months later that I noticed exactly how long I had been using it. the fact that I lost track of time spoke volumes to me, about how amazing this pen was. I knew that I had to order more.


The clip is one of the aspects of the pen that I really can’t talk about too much as I’ve never kept this pen in a shirt pocket (I don’t usually wear shirts with pockets). I’ve almost exclusively kept it in my Nock Co. Hightower that I take to school with me every single day. I’ve been using this particular DX in the photographs for almost 5 months now and the clip still looks as if its brand new. I don’t see the traditional slightly upwards bent state that some of my other pen clips have shown after constant use (namely, sliding them in and out of my pencil case).

There you have it folks, the reasons why I think that this is my perfect micro tip gel pen. The grip is slim, yet comfortable, the tip lays down a smooth and consistent line and the clip is rugged and reliable. This pen satisfies and goes beyond all the standard requirements I have for gel pens and that’s why it is #1 in my Top 5 Pens list under Gel Ink Pens. Give it a try and see what all the fuss is about. Until then, write on, my friends.

Uni Signo RT1 Review

Note: A thousand apologies to all my dedicated readers. In my infinite wisdom I scheduled the review for today and next week instead of last week and today. I was wondering why nothing was happening on my blog… derp. I shall endeavor to appease by putting this one(last week’s review) out today and this weeks review out tomorrow. Two reviews in one day would be rather strenuous. Along with these two will also come next weeks review, as an apology.Tomorrow’s review involves paper. Feel free to guess in the comments section or on IG or Twitter. Studying for my second round of midterms made it a little difficult to check out the blog stats. I’ll make sure to check at least once whether my scheduled posts go up. Thank you for all your support, I couldn’t do this without you. Now on to the review.



The tip is a small size (0.38mm), but it lays down a smooth crisp line that glides over the page, albeit with a little bit of feedback due to it’s extra fine nature. I couldn’t be more happy with it as I felt it’s performance was similar to the vaunted (and rightfully so), Uni Signo DX 0.38. This pen feels like it’s futuristic, retractable cousin.


The clip is integrated into the knock. It is rather convenient as it really seamlessly blends into the pen allowing the clip to remain out of the way while maintaining function.


Doesn’t it look like a futuristic rocket ship? I tried so hard to get this one shot until just the two tips were clearly in focus. Looks pretty cool to me.

Uni Signo 307 Review


This pen is the successor to the Uni Signo 207. This has taken what was probably Uni’s most successful design and further improved upon it. Now most of the pens I tend to review can’t be found at your Staples. This however, is the exception to the rule. Present in nearly very department store I’ve gone to, it is the most widely available gel ink pen I have reviewed to date.


The first thing I noticed about this pen was the ink. It wrote like butter straight out of the bubble wrap. I just touched the tip to paper and the ink just flowed naturally. As of writing this review the 307 is only available with a 0.7mm tip. However, there is a huge variety of refills with sizes ranging from 0.28 to 0.5. The refills are available in a large variety of vivid colors as well. I chose to stick to black, as I don’t use red too much and I have too many blue gel ink pens. It lays down a crisp bold line with high consistency. I have yet to experience an interruption in ink flow or blobbing on the page. The ink is pigment-based, which allows it to form a permanent bond with the paper. It is also billed as water-resistant, acid-free and of archival quality.


There are long ovular protrusions in a grid like pattern along a 3/4 length of the total grip section. These protrusions are my favorite aspect of this pen. As someone who tends to have sweaty hands, as I have iterated many a time in previous posts, the grip is one part of any pen that I critique on a higher scale. So it won’t surprise any of you that I love the design choices taken with this grip. It provides a lot of traction while not digging into my fingers when writing for long sessions. There is a “dorsal fin” like part of the grip that separates my thumb and index finger. It is reminiscent of the cap on the Nakaya Dorsal Fin v1, though not as pronounced. I find that it helps against “death grip” by spacing my fingers out. As a fellow with big hands, I don’t know what it would be like for those with smaller ones. So as a disclaimer, I will state that it might be a little uncomfortable if you like to place your index fingers near the center. Compared with the fin of the 207, the 307’s is more distinct from a tactile perspective.

All in all, definitely a great pen. Based off a very successful design I’m absolutely sure it would be. Though I have to say it took some time getting used to the grip’s dorsal fin. I found myself maneuvering around it many times during the first week. It eventually became a more useful addition to me later on.
