Uni-ball Signo UM-100 Gel Ink Pen - 0.5 mm - Blue

Sorry. I meant blue not black in my review.

This is a great pen for 0.5 mm. It is a deep black and doesn't smear if you give it like 4 seconds or so. Smoothness wise I think it's not ubber (yes, I said ubber) smooth and the flow of ink is very good. It would be a good pen to write a lot with if you don't have any problems without a grip. The barrel is very simple plastic barrel. This pen is a pen worth buying thought.(:

This is the best gel ink pen I had ever used. 'Do not judge a book by its cover and price', the pen may be in an economical body, but the writing performance is extremely fantastic! Absolutely no skipping of ink on any type of paper, very smoooooth, fantastic plastic barrel grip. Refillable too! Plus the blue ink is vibrant to me, compared to other gel pen's ink like Pilot G-2, which is dull. A very good pen for taking notes in lectures, makes my writing neat and vibrant! Try it! Great pen!

Excellent pen for note taking! nice, controlled and THIN lines, good size barrel, does not scratch onto paper, etc. This is my favorite pen for note taking for long periods!

Excellent silver ink pen. I just picked up a large sampling of different brands of metallic pens on Jetpens to find the best one, and I think Uni Signo UM-100 is my favorite! (I just wish the gold UM-100 would come back in stock because I reallyreallyreally want to try it too!)

Signo UM-100 silver is almost like a paint pen (without the paint pen smell) because the ink is so opaque, shiny, and pretty, and the pen writes soooo smoothly, I wish I could write everything in silver ink.

Like another reviewer said, I didn't expect it to work so well on light paper (because most silver pens don't show up on white) but the UM-100 silver shows up just perfectly on both light and dark paper.

I'll definitely order 2 or 3 more Signo UM-100 silver pens...just as soon as the gold UM-100 is restocked, hint, hint! ;-)
