This is a box of 10 black pens.

Uni-ball Signo gel ink pens 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!

Smooth ink flow, fine point. The only better pens I've ever used were the 0.18 uni-ball signo pens (which, sadly, are no longer made). If you drop the pens on a hard surface, yes they may stop working. But if you just use them at your desk, or somewhere that dropping risk is low, then they're *perfect*.

a really really really big let down. i have a bunch of these pens. and while they never stood out to me, they were the thinnest pens i'd encountered. i have tiny handwriting, so i just bought a few. i realized they worked okay, so i went ahead and purchased this set of 10 since i take notes daily. no. when i first got them, i was satisfied. thy worked, but they were uncomfortable to write with. it's like ripping your paper because the tip is so sharp and thin. the ink dries and skips ALL the time. i can't get through one sentence without it skipping multiple times. by the end of one weak, the ink was almost GONE. wow. and worst of all, even though there was still ink inside the barrel, the pen stopped working far before it got to the end. in conclusion, i'll say the pen is just OKAY, but sadly my expectations were not met. maybe i am not a fan of gel pens....maybe this pen was just not right for me.

For an artist, these pens are way better than the High-Tec C pens. They have a sturdy point, and they write exceptionally well over any graphite or pencils. The High-Tec C pens get kinda faulty when inking over pencils. They also dry fast and don't smudge.

I've made a terrible mistake!

I bought these pens expecting a sharp, smooth, quality pen that won't streak or smudge. While these pens won't smudge, that's about it - especially when they stop working! I've gone through half of my box already, wasting a good $12 so far. I'm really disappointed in these pens by how easily they just seem to stop working!

I hope JetPens will perhaps offer me some consolation, but I doubt it. For now I weep, and urge anyone else to not buy these pens if they expect to use all the ink before kicking out. 2 months in and I've been through 6 pens!
