## Overview

The Uni Ball One Gel Ink Pen Set features an ultra-fine 0.38mm tip paired with a newly developed quick-drying gel ink that delivers vibrant, bleed-resistant colors across 8 shades. Designed with a sleek, minimalist shaft and a movable clip, these pens combine professional style with smooth, reliable ink flow—ideal for detailed note-taking, journaling, and everyday office use.

## 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: Super fine - These pens come in nice colors. The level of pigment in each color is perfectly opague, not see through or weak. At .38, the ballpoint tips are very fine and serve their purpose well when it comes to having to write in small spaces or your particular handwriting style is to write in very small print. This also makes them perfect for writing notes in the margins of your favorite book or Bible.

## 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

### ⭐⭐⭐⭐⭐ Smooth writing, great colors and great quality
*by M***O on November 9, 2025*

I LOVE these pens! Smooth writing, great color, which helps me organize my daily work. The .38 ballpoint helps when I have to write small and clear. As a teacher, these are part of my go to supplies. Yes, I have to buy my own supplies and this is why I want quality, great prices (when on a sale) and the colors. The colors add another layer of organization throughout my day.
