Uni-ball Signo UM-151 gel ink pens, also known as Signo DX, are known for their smooth writing and exceptional ink quality. And, to everyone's delight, there is a sea of colors and tip sizes to choose from. Find the perfect pen for any task, whether it's writing meticulous notes, marking your calendar, or decorating your scrapbook with colorful captions.

Everything about this pen, from its solid construction to its carefully-formulated ink, ensures a wonderful writing experience. The sturdy tip does not bend or break, even with heavy-handed use. The pigment-based ink flows smoothly and is waterproof, fade-resistant, and feather-resistant. Much of that is due to special viscous properties of the ink. The ink is viscous while in the barrel, but as it passes through the pen tip during writing, the viscosity drops. This results in smooth ink flow. Immediately after it hits the paper, the ink returns to its viscous state, which prevents feathering. You are left with beautiful clean lines that you can enjoy for a long time!

I LOVE this pen, and...

I LOVE this pen, and all the DX UM-151s. I teach at the U of Utah, and this is the pen I use to grade all of my student's papers. The tip is fine enough that I can make little corrections in the margins and between lines; the "Bordeaux Black" color is red enough to seem like it's chastising my students for their silly mistakes, but not so red that they feel violated (turns out that bright red pens have a negative effect on students); and the smoothness is unlike any other pen with a tip this fine. The "blotchiness" that another reviewer mentioned is, for me, more like a fountain pen's "flair" once you get more used to it (perfect for writing kanji). Finally, one of the greatest features about this gel pen compared to every other gel pen I've used is the speed at which it dries--it's a smooth, fine gel ink that won't smudge. Awesome, awesome pen. Also great for writing in the margins of books.

I absolutely love these...

I absolutely love these pens. I have the black and the bordeaux black in 0.38. The line thickness in perfect for editing small text and writing notes. The tip is very sturdy yet delicate. I love the feel of this pen. Good weight--not too heavy nor too light--and the plastic barrel fits my grip rather well. It is a delight to write with and I LOVE the bordeaux black color, in fact it might be my favorite color at the moment. My one complaint, and it is very annoying, is that the ink frequently runs dry and I need to scribble on scrap paper to get it going again. This is the one reason why this pen hasn't surpassed my other two favorites: the Hi-Tec C and the Slicci 0.4 pens.

I am completely in love with this pen. The color is very nice and crisp, but also really classy. The BEST color to edit or grade papers/tests/homework with. It stands out really well from the paper, no student you grade will have this same color to try and change your grade markings and it is not nearly as aggressive as a bright red. I personally have always hated having my work corrected in bright red- it's both demoralizing as well as an eyesore. The ink is extremely smooth and you can write very quickly with this pen, however it is not nearly as fine as other 0.38 mm pens I've used (such as the uni style fits) and it feels a little more clunky than I was expecting. Almost as if the thickness isn't very consistent, but I prefer that to a pen that often skips. Dries quickly and have had no problems with smearing. Wish they made it in 0.28 mm.

This is my go-to correction...

This is my go-to correction pen. I like to type stories, but when I edit them I opt for printing out the whole document and writing corrections/edits by hand. This pen is perfect. It’s small enough for me to get into the tiny margins, but bold enough for me to write without it feeling scratchy. I love the pen so much I had to order the full color range!

As for this particular color, what I like about it is that it’s a great option against red. Red is a bold color to use for correction, as it stands easily out from among the text. But no one likes seeing red on their own paper—even me. It’s darker than red, a more darker purple of color, but not enough of the royal hue to make one think that it’s violet. Overall, this is probably my most favorite correction pen and color combination.

This is a wonderful pen....

This is a wonderful pen. It's a little more fine point than I normally use, but still easy to write with in those spots where you need a very fine line. Ink flow is perfect, in spite of the fine point. The ink color, which is a perfect mix of red and black, was a revelation to me. It's a subtle color, very pleasing to the eyes. The pen is well made also, and feels good in the hand. Well worth the money!
