uniball one Retractable Gel Pens, Micro Point (0.5mm), Black Ink, 12 Pack

I was very excited to receive these pens. I like to use a good pen that is easy on your hand to write with, especially when doing a lot of writing and studying, as this is essential. I love TUL pens, but for this particular use, BIBLE study, marginal comments, and so forth, I did not want the bleed-through that some pens afford. So, my search started, and EVERYONE commented on the excellence of these pens, ease of writing, no bleed-through, crisp, sharp, fine lines without skipping, smudging, or smearing. Well, these pens tick off all those points for me, too. All the Uniball pens I have purchased are excellent and meet my needs; the micro point is a true "fine line" pen, the colors are good, and they dry quickly if not instantly. I will continue to use these as one of my favorite pens for BIBLE study. I am very pleased.

I don't usually get emotional about office supplies, but these Uni-ball One pens? They changed me. The ink glides like it's on a mission from the handwriting gods. No scratchiness, no hesitation, just pure, silky lines that make my grocery lists look like calligraphy written by a monk with perfect posture. The 0.5 mm tip is sharp enough to slice through my existential dread but gentle enough for even the most fragile Post-it Note. It dries fast too, which is perfect for lefties, impatient people, or anyone who’s ever accidentally dragged their hand across freshly written text and ruined both the paper and their will to live. The clip is strong, the click is satisfying, and the pen feels expensive enough to trick people into thinking I have my life together. I bought the 12-pack so I could lose 11 of them slowly over the next year like a true adult. If you want a pen that writes like a dream and makes you feel 10% more competent, get this. Then write a thank-you note to yourself in perfect, smudge-free ink.

I love this pen so much that I go out of my way to find reasons to use it. I wasn’t sure I was going to like it at first but it’s actually perfect for my writing preferences. It has a slim body, comfortable grip, smooth and quick drying gel, with a precise fine-point nib. The pen feels light weight and sleek. I haven’t had any trouble with it skipping ink or fading out while writing. I also have no problems with my writing smearing (right handed). But just a word of advice, if you’re going to use a highlighter over your ink, then let the ink dry really well first. Whenever I highlight the ink before it dries it will definitely smear BUT when I properly let the ink dry first, then it’s perfect, no smearing! I’ve been using 1 pen EVERYDAY (out of a pack of 5) and so far it’s lasted me a LONG time. I still have 90% of the ink left in just my first pen. I consider this Uniball One pen to be both great quality and good long term use. I will absolutely buy them again in the future. I might consider trying out some of the other ink colors as well.

I do like these pens overall, but I've had an issue with ink skipping. The pens do still have a rich black color, and the ink dries faster than any other 0.7 pen I've used.

I recently tried this Uni-ball gel pen and it has quickly become one of my go-to writing tools. Here’s how it stacks up. ✅ What I liked • Smooth, reliable ink flow: The ink lays down dark, crisp lines with very little effort. One reviewer said the ink “lays down clear dark lines with every motion.”  • Minimal skipping / interruption: For many types of paper I’ve used, it writes without hesitation—no major skips or gaps in the line. (Although some users do note skipping on lower-quality paper)  • Comfortable barrel & design: The pen has a good balance, a comfortable size and shape, and doesn’t feel cheap or overly lightweight. The “One” series for Uni-ball is described as “a perfect length and diameter… comfortable for longer writing sessions.”  • Quick drying & less smearing: Especially helpful if you’re left-handed or write quickly—less chance of smudge after writing. One review: “great choice if you’re looking for a super smooth writing experience… but the smudging issue holds back perfection.”  • Good value: For the performance I got, I felt the price was reasonable. It’s nice when a pen does more than the basics. ⚠️ Areas that could be better • Paper dependence: On cheaper or very slick paper, some users mention skipping or inconsistent flow. As one Reddit user put it: “The Uni ONE is a nice pen … but the refill is a let down on reliability. It does skip on the type of cheap paper pad I use.”  • Tip/point size & color limitations: Some of the finer tip sizes or lighter colors (in certain series) are less bold or harder to read. One review of color variants said: “Some of the colors were a bit light for the 0.38mm sized tips… writing is challenging.”  • Grip style: A few reviews mentioned that the grip section is smooth and lacking heavy rubber texture, which might make it slightly less stable if you write for long hours without break.  🎯 My Verdict If you’re looking for a high-quality gel pen for everyday use—notes, journaling, office work—this Uni-ball One gel pen is a strong pick. It gives you smooth writing, good design, minimal fuss, and consistent performance. If you’re using extremely cheap paper, or you need the absolute finest tip for ultra-detailed drawing, you might want to check whether the specific variant meets those needs. But for general use, it hits the mark. I’m keeping it in my rotation and will likely buy another in a different color or tip size. ⸻ If you like, I can also write a shorter “quick review” version (1-2 sentences) or a version tailored for a specific use case (e.g., for left-handed writers, for bullet journaling, etc.). Would you like that?

Very thick dark ink, smooth, decent grip, good size and a very nice looking pen. My complaint is that im on my third pen of these and they have ALL skipped. I can hardly write a full sentence without the pen skipping.

By far my favorite pens to write with. Smooth ink with no bleed or smudge

These uniball one Retractable Gel Pens write smooth and they don't smear when writing. They feel comfortable to hold and grip.

Caneta maravilhosa

Não vale a pena! as canetas são até legais no design, só que a tinta falha, portanto não serve

For buttery smooth writing , 0.5mm is a personal favourite.

Suaves , pintan bien.

Great product and delivery. I writes beautifully smoothly and dries fast.
