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.
