Best Pen I Have Ever Used!
I'll admit it...I'm a pen snob. I love writing (both the craft of forming letters with a good pen and the art of expressing myself on paper). No doubt, that is why I enjoy writing product reviews. However, when I write, I want a good pen in hand. Sure, often I compose at the keyboard. However, when I have writer's block, I pick up a good pen like this Uni-ball Signo Um-151 Gel Ink Pen. It just seems to get my creative juices flowing. The first day, I noticed the tiniest hint of scratchiness with this pen. After using it for a short time, it seemed to go away. Either I broke the pen in, or I got used to it. Whatever, I adore this pen and all its features. I recently tried these Uni-ball Signo Um-151 Gel Ink Pens for the first time. I thought I had tried almost every micropoint pen on the market. Obviously not. These pens are absolutely fabulous: . 38 mm micropoint . metal tip . gel ink . no smudging or leaking . open Es, As, and Os no matter how small you write . instant drying ink . smooth writing/beautiful lines . comfort grip . round barrel . snap on cap . pocket clip . long lasting .very reasonable price ($1.50 a pen) This is a five star pen in my book. I'm going to have a hard time finding a pen that can beat this one at this price. Very highly recommend to other lovers of micropoint pens! Love it!

These are my absolute favorite pens!
I love these pens and never want to be without them. I keep a few boxes in my desk drawer and really like that Amazon sells these by the box at an affordable price. The pens themselves are simple but very high quality. What really sets these pens apart is the way they write, smooth, reliable, and precise. Highly recommended.

THE best pen I've ever used in the world... better than Mont Blanc!
I Love these pens! Years ago i've gone to asia hunting for these pens in many many stalls, shops and stores. Easily THE best writing utensil I've ever used in terms of quality of ink, feel of the pen, and the overall look of the writing. The ball on the ballpoint is very smooth and high quality, not like those cheap american pens you get even at high prices. It's very smooth writing. I also like the thinner writing size. 0.38 I feel is the perfect size and balance between readability and practicality. I also own the 0.28 variant of this pen, and while I felt you can fit more words on a page with a thinner writing pen, it becomes hard to read at times because of how small the words look. I've also used many brands of 0.38 pens that you can find at Staples, office depot, office max, and various stationary stores around the world, but nothing comes close to this one. Even Mont Blanc pens are not as smooth writing as this one. And for the price it's just the best. The only thing i wish they had was a physically shorter and slimmer version to carry in your wallet.

Great pens!
I was skeptical about gel pens as other ones I have used leak somehow or smudge. These were perfect - no smudging, lines are crisp and clean. Does the job!

I like pens that don't click... people abuse that feature
These pens are awesome for those who write small or have big brass ones and do math with a pen - they write smooth and the ink doesn't smudge, however, every now and then they have trouble writing on the color printouts from the company laser printer. I will buy another box as soon as I go though these, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that, and another box after that... you get the idea

Mid-tier Pen Worth the Price! People Will Notice This Pen! Do Not Lose This Pen!
A great pen for signatures and general writing where you need the writing to show up on photocopies and scans to online documents. Be aware that this ink flows faster than ball-point pens, so you'll run through a single pen in a couple weeks if you use it for writing journals or logs (You'll see it drain by the day or hour depending on use). The point is sharp and will tear or puncture paper without a hard supporting surface (cardboard and clipboards are ok). Be careful not to hurt yourself with the tip! That same sharp point can also come in handy for self-defense and pressing reset buttons, but beware that the tip may break if you do this (see way below). This pen is normally not available in local stores like Staples or Office Depot. I bought the .38 originally for writing logs, as wider tips made fitting numbers and letters into small blocks difficult. The grip is comfortable and the pen is surprisingly light and balanced when the cap is removed. I leave my cap on, as I am used to writing with weighted pens (I am also less likely to lose the cap). Be advised: Although these gel-pens are a vast improvement over Pilot G-series pens (as they will not explode or leak giant random globs on the paper) the plastic mechanism in the tip may break, causing the pen to sometimes not apply ink mid-stroke or not at all. I usually switch over to another pen in that case, as there are quite a few pens per pack. Consider buying at least 2 packs if you intend to use these pens as your primary writing instrument. Overall, it is worth paying $1.50 / pen for it's intended use. People take notice when they borrow this disposable pen. Be sure to get your pens back! They're hard to come by, good quality, and cost money!

I've been using Uni-Ball One Gel 0.38 pens for some time as well as Pilot Juice Gel 0.38 pens. But as they're pricey, I decided to try the Uni-ball Signo DX. I like the flow of the Uni-ball Signo DX way more! The flow isn't constant with the Uni-Ball One Gel or the Pilot Juice Gel 0.38, whereas the flow is more constant with the Uni-ball Signo DX. The black pigment is the same among the three pens. Overall, for the price, the Uni-ball Signo DX offers excellent quality!

文房具店から商品が無くなっているような気がするのだが思い過ごしだろうか? 紙との相性でこのペンに勝るもの他になしというくらい気に入っているので「箱買い」も全然苦にならない

They write clearly, perfectly thin lines, the ink is not super smudgeable! I write small and I drag my hand on the page when I write and I only use these pens because the ink flow is consistent and I do not get ink all over my page or on my hand.

なんでもメモする習慣があり文章を書くのが好きな私は、かなり昔にいろいろなボールペンを買って書き比べをした事があります。 そんな中で字の太さやインクの出やすさが私に一番合っていたのが、このボールペンでした。 たまに他のボールペンを使うと、どうしても馴染めず、やはりこのボールペンでなければしっくりきません。 だんだんとスマホのアプリでメモを書く機会も増えてきましたが、それでも実際にボールペンで文字を書くのが好きなので、このボールペンをまとめ買いして切らさないようにしています。
