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

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.

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 absolutely love the size of the pens and the size of the tips. I think I’ve received a bad batch because I’ve only used them over a two day span and barely used them and the ink isn’t coming out. I’ve tried on different textures of paper and still not performing like I’d hoped. The colors of the ink are simply beautiful. Oh I Pray I can exchange and the next batch will be better because I really do like using these. ‼️‼️update‼️‼️ I did not return this item. Instead I looked up way to get ink flowing again. I found using lighter 🔥 to heat the metal tip works wonders.

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.

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.

Love these refills for my uni style fit pens. Love that they come in a pen ready to be used if you don't need them for refills. Very cool.

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 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.

Awesome, ive put a few in my uni style fit ( bought separately) and they are an amazing refill. A good price for how many. They come in a case than can be used as a pen. LOVE wish I was rich so I could buy 10 times over.

I bus 1 hour to school. Bought to reduce the size and weight of my backpack. It's worth it. Pens write so smooth, bright colour. Barrel is thin at first and still an careful when using. The price is a bit high but, the advantage of carrying so many without bulk or weight.... It's does offset that.

Great

These write beautifully, and I love the array of colours!!! It's so nice to finally find a .28 nib! Please make more!!! In metallic would be sweet!

Nothing beats Japan made quality
