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.

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.

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.

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.

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 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.

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 own these pens in black, blue, and purple, and I use them to write in my small planner. They are perfect for fine, detailed writing, allowing me to write in tiny spaces. I also think they’d be great for writing kanji and making tiny notes. However, since the pens are quite thin, I can see how the grip might be uncomfortable for those with larger hands.

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!

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.

Nothing beats Japan made quality
