Uni-ball StyleFit Retractable Gel Ink Pen (UMN-139-28), Slim & Stylish Body, 0.28 mm, 16 Color Set

I first found and purchased these pens in Japan. These writing utensils quickly became my favorite out of an entire arsenal of casings with various types of ink. They are slim, light weight, write smoothly, and the ink is well pigmented in every color. Most importantly is the fact these can be purchased based on preference from fine to medium etc. I will continue to purchase these pens as long as they are available. Highly recommend - I’d give 10 stars if I could.

I love a fine tip pen and these are perfect! My writing is so dainty and fine with these. Plus, the fact that they are colored is really fantastic as well. Often times you can only get black or blue in the fine tip.

These are wonderfully color dense and not scratchy despite being very very fine line pens. There's no clip on them and they're VERY slim pens, so using them with the elastic loop in my planners is problematic. I keep them in a pencil case. These are very high quality very fine line ballpoints with good and saturated colored ink. useful and fun. They have not dried out or hard-started in months of use (a perennial problem with other fine line pens in my experience). Really good value for money.

These are by far my favorite pens! However, the ink has run out of 3 of the pens so far. They ran out MUCH quicker than I thought they would. Other than that, I LOVE these. They write smoothly, no breaks. The thinness is as thin as I can find with this many colors.

The colors glide on, they don't skip, they are vibrant and bright, for my line work it is going to be awesome. Did you see my picture? I can write so small! Think of all the designs I can fit. And break out the glasses. Also will try with my bible. I love all my other pens too. Just used for example for artists to compare. If the end that tapers proves hard to hold I will put washi tape around it to desired thickness. Don't not buy them because of that. Easily fixed with tape. I will be buying these again. And, does not smear with water! That's what I need for my fine line drawings. Super happy.

I love the .28mm Uni-ball StyleFit pens. The color variety is fantastic for the thin line option, not something that's common. The colors are bright and easy to read, even on the "lighter" colors like pink, yellow orange, and sky blue. A lot of ultra fine pens clog up or dry out, but these don't. My only wish is that the replacement ink tubes were as cheap and easy to purchase as a full set with the plastic holder. It's a waste of materials that makes me sad.

I can write chinese characters in 5mm grid squares thanks to these babies!!! (pink and blue characters are done with 0.4 pens, xeno and sarasa respectively)

The best pens if you like SUPER fine point. Very thin, easy to hold. Really enjoy the variety of colors, too.
