Gel ink refill component only. Compatible with the Uni-ball Style Fit writing system.

Uni-ball has created a new writing system that is both extremely customizable and affordable. Like the higher end Sharbo X from Zebra, the Style Fit writing system gives you the freedom of choice to create a writing instrument that is as unique as you are. You can customize many aspects of your pen including what type of refills you want (gel, ballpoint, or mechanical pencil), the pen body and ink colors that you want, as well as the number of writing instruments you want to have (different sized bodies are available that can hold 1, 3, or 5 writing instruments).

Each writing instrument line consists of the best that Uni-ball has to offer. The ballpoint line contains the famous oil based, water and light resistant Jetstream ink that writes incredibly smooth. The gel ink line contains the popular Signo ink that is the same as that in the popular selling Uni-ball Signo line. The mechanical pencil is pre-filled with Uni-ball NanoDia Low-Wear pencil leads, which are infused with nano-diamond pieces to create an unusually strong and high-quality lead. The combination of all the above allows you to create a multi-pen that has all the best Uni-ball qualities in one single instrument. In addition, the system is eco-friendly since you can refill it again and again.

Wow, this pen is really...

Wow, this pen is really something. I've had gel pens that were quite scratchy even at 0.38 but this 0.28 was quite smooth. I scribbled quickly in large circles and there was no skipping! The line comes out beautifully as it does in Uniball's regular gel pens. My job requires me to write lots of info on tiny cards and I've been looking for a pen that will lay down a fine line. The only problem is the cards have what I feel is a coating that seems waxy, which has caused gel pens I've used in the past to skip. Although those other extra thin gel pens didn't perform quite as well as this one does. The tip is solid, so no issues with bending a needle tip. Though, it is a very fine width, so I wonder if it would take damage anyway if the pen were dropped...

If you're looking for something in 0.28, this pen really delivers. The plastic casing the refills come in are also good for storing half used refills!

Best pens you will ever buy!!! .28mm, so definite and beautiful! The only drawback is you need to be careful not to drop the pen with these out or the tip of the own will kind of break and you'll need to replace the ink cartridge to get a good line again.

One of my go-to colors, standard black! Writes so smoothly and only minimally scratchy with such a tiny tip! I love writing color-coded notes as small as I want.

The tip of the pen is very fine, and it does write well and is very smooth. However, I don't feel like it will hold up to tough everyday use. I do not use it every day but only when I need to write very fine. I am going to order the .38's as I'm guessing the thicker pen may hold up better to daily wear and tear.

Overall, a good pen, very solid tip, and extra fine lines.
