uniball Zento Liquid Gel Ink Retractable Pens, Medium Point (0.7mm), Muted Barrels, Black Ink, Dozen

I’ve gone through countless pens looking for the right one, and the uniball Zento is hands down my favorite. 1. Incredible Smoothness: The liquid gel ink flows perfectly. There’s absolutely no skipping or scratching on the paper; it just glides. The 0.7mm medium point lays down a bold, clear line that looks professional. 2. Comfortable for Long Sessions: The ergonomic grip is excellent. It has just the right amount of cushion, so my hand doesn't cramp up even after hours of grading or note-taking. 3. Long-Lasting: These pens seem to last forever. I use them daily, and the ink supply holds up surprisingly well compared to other gel pens that run dry in a week. If you want a reliable, high-quality pen that makes writing feel effortless, pick these up.

LDR: Super-smooth, quick-drying black gel ink in an aesthetically pleasing, comfortable, and environmentally conscious barrel. A top-tier choice for effortless, smudge-free writing. I recently purchased the 12-pack of Uniball Zento Gel Ink Rollerball Pens because I was in the market for a reliable, super-smooth pen for long-form note-taking and journaling. My initial impression was excellent: the sleek, minimalist design is immediately appealing, and the moment I put the pen to paper, the writing experience was noticeably superior. The "medium point" (0.7mm) combined with the new liquid gel ink formula promised an effortless glide, and it absolutely delivered. In real-world use, the Zento pens truly shine. They perform consistently without skipping, delivering a dark, uniform black line that makes handwriting look crisp and clean. The biggest standout feature is the ink's quick-drying property. As someone who writes fairly quickly, smearing is a constant issue with gel pens, but the Zento ink dries so fast that it's virtually smudge-resistant, which is a massive win. The seamless soft grip is comfortable and helps prevent hand fatigue during extended writing sessions. The barrel itself, made from 76% recycled material, adds an unexpected layer of satisfaction to the purchase. The only minor point of consideration is that the black ink, while dark and vivid, is sometimes described as slightly lighter than the deepest black of some other Uniball lines, but this is a very fine distinction. Pros Super-Smooth Writing: The liquid gel ink provides an effortless, non-scratchy writing experience. Quick-Drying Ink: Significantly reduces smudging and is excellent for fast writers and left-handers. Comfortable Grip/Design: The minimalist barrel with a seamless soft grip is comfortable for long-term use. Eco-Friendly Barrel: Made from 76% recycled plastic, aligning with environmental consciousness. Strong, Functional Clip: The spring-loaded wire clip is durable and easily attaches to notebooks or pockets. Cons Ink Blackness: Some users find the black ink, while very good, is not the absolute deepest shade of black compared to some other premium gel pens. Refill Availability/Compatibility: While the pen body is refillable (often taking other Uniball refills), the specific Zento refill may not be as universally available as others. Verdict The Uniball Zento Gel Ink Rollerball Pen is an absolute winner and easily warrants a 5-star rating. It is best for anyone who values a remarkably smooth, quick-drying, and consistent writing experience for everyday use, professional work, or intensive note-taking. If you've been looking for a reliable, smudge-free pen that is both aesthetically pleasing and comfortable to hold, the Zento is well worth the price.

Excellent set of pens! The ink flows smoothly and consistently, the writing feels comfortable and does not run. Perfect for daily tasks, notes and quick notes. Very good quality for the price, I would definitely buy them again!

These are really good pens. They write smoothly, no skipping, and the feel good in your hand. The ink flow is great. No problems. And the price is right. I have other pens, but keep reaching for this one, the Uniball Zento. I look forward to Uniball making other colors.

These pens are very pleasant to use. The design is soft and nice, and they feel comfortable in the hand. They don’t slip while writing and don’t make my fingers hurt or tired. The grip is gentle, so there are no marks on the fingers after writing. The ink goes on very smoothly, almost like the pen is sliding across the paper. The color is rich and consistent. There are no skips or breaks in the lines, and the pens work very well every time. Good quality, smooth writing, great design, and very functional. A really nice set of pens.

Love writing with them but go out if I am using for a long period and and to re write a letter or two. Will buy them again.

I really love these pens. The ink flow is incredibly smooth, and the minimalist design looks great. While it maintains the high ink quality you expect from uni-ball, these pens dry much faster and smudge significantly less than others, making them ideal for writing in planners or notebooks. I also really like the design of the clip. If I had one request, I would love the option to buy a pack in a single color. I personally prefer the "boring" look of just all-white or all-black barrels rather than a color assortment. Overall, these are fantastic, high-quality pens.

I’m very satisfied with the Uni-ball Zento Gel Ink Rollerball Pen. The ink flows smoothly with no skipping or smudging, and it dries quickly. It’s comfortable to hold and delivers clean, consistent lines every time. Great quality and definitely worth buying again.

This is one of the best pens I’ve ever used. It has bright ink and smooth tips that glide through paper effortlessly.

Escrita super macia e agradável.

Seen some online reviews and they were really impressive. The pen isn’t that good as they say but it’s really good tho. I like it
