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!

Note: The Pink ink color is almost fluorescent. It is brighter than what we are able to show in the writing sample photos.

My daily pens are the Pilot G-2 .38 mm and the Pilot Hi-Tec-C pens. If you like either of those, you will probably like these just fine.

I prefer both pilots to these Signo pens, however, I use the Signo pen exclusively in my chemistry classes where my papers / notebook is very likely to get wet. These are waterproof and my lab notebooks are no longer a big blur after class! Also, the plastic box / case they come in is very generous in size and is perfect for storing additional highliters, pencils, erasers and paperclips. Highly recommend these pens!

I love very fine point pens. I have had a lot of trouble finding truly good ones. That is until visiting a friends house and picking up a pen to write down some information. The only word that comes to mind is WOW! A gel pen that won't run, won't smear, yet is a smooth writing instrument. I had to order my own set.
If you like a wide range of brilliant colors, a fine tip, an all around great writing experience order these. You won't be disappointed.
Oh, and the speed of shipping, excellent. The packaging-excellent. (I live in an area that usually takes longer than most to receive anything.)
I will be ordering more, to complete my colors.

I actually spent all of last weekend looking for some good pens to replace my G-2 pens which I currently (well, now it's previously) use. And I must say, these pens are great!!! I bought these pens in the 10 piece set in .38 mm and I love them so far. The quality of these pens are great and are superior to that of the G-2s. For note of reference, the G-2s I had had a 1.0 mm head thickness. And man, what a difference does pen head thickness make. I can now draw intricately and delicately as well as being able to write much much smaller. I would recommend these pens to anybody who values quality pens.

On a side note , I also bought 1 Pentel Slicci and 1 Pilot Hi-Tec-C in .3 mm each just to test them out. Even those pens produced much finer lines, but these pens did not have plastic grips on them. I think the next time I order these pens I will get them in .28 mm thickness. No complaint about these pens, guys, definitely worth the $!

Love these pens. I had stupidly purchased some gel pens from a local general retailer and then regretted it. The cheap gels I bought had ink consistency issues. I'd be writing (and I tend to write fast), and all the sudden, the ink would stop flowing or be extremely light (i.e., railroading), which was frustrating, especially when taking notes in meetings. Enter JetPen's guide to fine-tip gel pens. I opted to go with the Uni-Ball Signo UM-151 because of the precision, the lack of railroading, the selection of colors, and option for tip sizes.

Now that I've tried them, I love them. They write so smooth, so precise, and dry fast. I love the color variety and use the colors when editing documents or taking notes. Plus, they come in their own carry case. Would highly recommend to anyone who likes precise, smooth writing, and tends to write fast.
