## Description

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

Review: Best pens in the world. - These are my FAVORITE pens. I've been using this style pen for over a decade and will continue to use them for as long as they are made. You'd be hard pressed to find a set of pens with a finer point and greater range of colors. No issues with ink smearing or anything. Truly no complaints about this pen. Highly recommend to anyone who loves a fine point.
Review: Beautiful colors - 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.

### ⭐⭐⭐⭐ Writes amazing, but very narrow barrel with no grip and no clip
*by M***I on September 12, 2025*

The overall pen is of middle quality. The barrel is nice but not fancy or ergonomic, there is no grip or cushion. If you like a bulkier grip, this may not be for you. The body of the pen is pretty skinny and many of the after market grips available would be to big to help. They write beautifully for such a fine tip. I haven't noticed any significant skipping or scratching that sometimes happens with extra fine tips. The only thing I would add is some kind of clip, but I think part of the marketing is the simplicity, streamlined design while still being retractable. The colors are amazing. I wish all these multi color pen packs in the extra fine tips had more purples and greens, way less yellow (like none, if I'm honest) and maybe a few less blues. But this color selection is actually better than a lot of them.
