uniball™ one Retractable Gel Pens, Medium Point (0.7mm), Black Ink, 5 Pack

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?

The Uniball One Gel pens are a high quality pen at a reasonable price that because of the quick dry pigment based ink do not smear or smudge, even when touched quickly after writing. The 5 pack comes with 5 different colors. The ink stays on top of the page and does not bleed through at all, even on a Bible page, which is much thinner than most other media. This allows the pens to be used (different colors) for taking notes in a Bible without degrading the underlying page or making it harder to read. They have a good grip, feel good in the hand, and come in a large variety of colors. They write smoothly and perform well.

Great pen the only problem is everyone who uses them wants one. Funny how everyone notices a good pen when they have it in hand. Writes beutifully and feels good.

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.

This is my new favorite pen. I use it for all of my household list and general correspondence. It is comfortable to use and has smooth ink delivery. That’s just what I need in a “go to” pen. The medium sized point leaves a bold stroke that doesn’t weep through the paper to the opposite side.

They work well for the first couple days then start skipping to the point i'm going over every letter again. Very frustrating because i love them otherwise.

I will be honest and say that I have not written with this pen much as of late, as I recently switched to what I would consider this pens ballpoint counterpart, the Jetstream RT (you can check my review of that if you are interested in ballpoint pens). As for the Uni-Ball One Black Retractable Gel pen, I will start off by saying that I have primarily used Pilot G2 pens probably since they came out, and within the last few years added TUL. One of the biggest problems that I have with both the TUL and the G2 is the smudging. It just takes too long for the ink to soak in to the surface or dry. The Uni-Ball One Black does NOT have that problem. I am not sure of the exact science behind what they have done with their One-Ink, but it is quick to dry to most paper. Overall, this pen is just comfortable and feels solid in the hand. I like the size of the barrel, and the clip may look as though it will be flimsy, but it is constructed well. The price is very reasonable, and the color...if you want your ink to be the blackest of blacks, this is your pen! Once they get the color spectrum that TUL has, I will likely make the full switch to Uni-Ball. Keep up the great work!

My favorite pens. Smooth writing, doesn’t leak or smear ink. I use for work and these do not hurt my hand ever ergonomically styled. Would recommend for someone who uses pens on a regular basis.

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.

I just love these pens- I’ve fully switched to these over others. Easy flow of ink and the clip is very sturdy which means it doesn’t break when you play with it (don’t we all do this?)

Uniball ONE bolígrafo de gel, 0.7 mm surtido de colores, llegó en la fecha programada, dentro de una bolsa de Amazon en su empaque original con daño leve en las esquinas durante el transporte quizá porque es un paquete pequeño, sin afectar el contenido. Es tal como lo describe el vendedor. Ha superado las expectativas, en especial por el tono vivo de sus tintas, que es agradable a la vista. por lo demás es de calidad superior. Vale cada centavo invertido. Merece ser comprado una y otra vez.
