Uni-ball Style Fit Single Color Slim Gel Ink Pen - 0.28 mm - Black

It's great for drawing. The ink is nice and dark and makes a beautiful smooth line. I would highly recommend this pen for artists!

Not a very good writing pen, but great for fine short notes or color coding in small areas. I love how fine they are. They're a little too thin to write for very long with (gets uncomfortable) but they very rarely clog or skip. I bought the pink green and blue and those three at least have bright colors which I use to color code my notes with.

I like the concept of this pen very much. Easy and portable but there is not a good grip on it and it is scratchy when I write on "american" college ruled paper. I would recommend the Uni-ball Signo DX UM-151 Gel Ink Pen over this. It is a few cents more expensive but it is a better pen overall.

OBSESSED with these pens. I have a few colors, and use them daily. I have one in my wallet, as they are so slim that they fit well tucked away where you need them. These are the only pens I currently use in my daily work and home life. The ink is so smooth and the line so crisp that you'd actually think it thinner than its 0.28 mm measurement.

I have continually ordered these, despite at first being weary of such a slim pen. I wasn't sure it would be comfortable to use, but they are truly awesome. I have used at least three until completely empty and never had a break or clog in ink flow like other thin gel ink pens. This is what I wanted the Uni-ball Signo Bit UM-201 to be. The ability to see the ink level is an added bonus.

I highly recommend these for anyone who demands thin, crisp, continuous lines in their day-to-day writing at a low cost.

I think this is my favorite fine drawing pen now. Works wonderfully well on the grained paper of the Maruman Mnemosyne - Word Book - 105 mm X 54 mm - 100 Sheets. Smooth and very fine. I've been using it to draw very fine art cards, and I absolutely love it!
