## Overview

The Uni-Ball One Gel Ink Pen Set features an ultra-fine 0.38mm tip and a newly developed quick-drying gel ink that delivers vibrant colors without bleeding or smudging. Designed with a sleek, minimalist shaft and a movable clip, this set of 8 colors offers professional-grade precision and smooth ink flow, ideal for detailed note-taking, journaling, and everyday writing needs.

## Description

Uni New Gel-Ink Ballpoint Pen, "Uni-Ball One" has appeared. Uni-Ball One features a newly developed gel ink and a simple shaft design. The new Uni-Ball One has a deeper black color and a more vibrant color than typical gel inks, and can create impressive notes that will look sharper when you look back later. General quick-drying ink achieves quick-drying by increasing the penetration of the ink into the paper. As a result, ink bleeding or strike-through sometimes occurred. The newly developed "Uni-Ball One Ink" enables the liquid component to quickly penetrate into the paper by changing the ratio of the solid and liquid components in the ink, while allowing the solid color material to remain on the paper. Although it is a quick-drying ink that penetrates the paper quickly, it does not bleed or strike through to prevent the color material from being absorbed into the paper. The shaft design is simple and straight. The color ink uses an off-white axis color that blends into the living space, resulting in a calm impression. The oval-shaped "open wire clip" has a stylish design and is a movable clip that can be easily inserted between notebooks and notebooks.

Review: Nice, colorful journaling pens. - I loved these pens for journaling. I enjoyed all the different colors and the general quality of the pens. I could use certain colors to help get a seasonal or holiday visual for the month. They have a nice, fine point for writing small, if needed. They did not bleed through the paper. The ink flow is smooth and does not skip or fail to lay down. I did not have any problems with the ink drying time, either. I like that the tip retracts. I also like the easy grip surface of the lower portion of the barrel. The only problem is that I wish they sold sets of multi-colored refills. Journaling uses quite a bit of ink, and I sure do not like to just dispose of the whole pen when the ink runs out. That is not environmentally friendly. And, it will be confusing to just put say blue or black refills in all pens that have different colored tops.
Review: AMAZING! 👌 - This might be my new favorite ballpoint/gel pen! I loved everything about it: packaging, sleek design, colors, weight - everything is so well thought! As a leftie, I struggle with smudges and bleeding, and I’m happy to report the ink dries incredibly fast, and there wasn’t any bleeding ( I tested the pens on a post it pad). I can’t speak on skipping yet, but I am confident it will perform well during long writing sessions.

## Questions & Answers

**Q: do you also sell ink refills for these pens? I'm looking for blue**
A: These pens do not write well at all.

**Q: How do these compare to Tül pens?**
A: Well TUL has a larger ball base than the UNI. I find a thinner base more functional

**Q: Does the ink show up on black paper or is it just for white paper?**
A: Just for white, I have been looking for a milky equivalent. I keep hoping they will make some :) since these are my favorite.

**Q: Is the ink archival and waterproof?**
A: As far as I can tell yes

### ⭐⭐⭐⭐⭐ New fav from a sharpie pen lover.
*by A***M on March 8, 2026*

These pens are bomb. I love them so much. I love the precision with the .38 mm and it’s a clicky pen!!! It writes so smooth. The design has a fidget built in so you don’t have to annoy people. They have not smeared once, but I haven’t ran a highlighter over it yet.
