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!

This is the Blue Black pen. The close-up tip photo features the Black pen.

I am a HUGE fan of both the Hi-Tec and Slicci gel pens. I tried these on a whim. They have become my favorite gel pen ever! I like the 0.38 mm tip best, but the 0.5mm is preferred by my best friend (who is constantly borrowing my writing implements). The colors are great, they write smooth and aren't scratchy (a problem I have with Slicci pens). Definitely worth the cost: I am slowly replacing all my other gel pens with these. BTW: black-brown is an AWESOME color!

Okay, I usually shy away from 0.5mm tip pens, and prefer something along the lines of 0.7 or 0.8. I find that 0.5mm pens are too scratchy and just make for an awful writing experience. My problem is I like blue/black. So I gave this pen a try, and I am now proud to say it is my pen of choice. Their is no scratchiness too this pen at all and the pen just seems to glide across the paper. Even when I am writing in script very quickly. Which has not been my experience with pens such as the vision elite 0.5. It's awesome and the blue/black ink is just classy.

This is my all time favorite pen. I own it in other sizes and colors but 0.5 blue black is the very best.
Like all uniballs it writes very smoothly. I don't even mind taking the cap off to write. I've been ordering this pen for years
