Marvelous pen, marvelous ink. Best i've tried.
The best pens for free flowing fast writing, either lettering or cursive. The 0.7 mm is preferable for cursive, rather than smaller tips. The rubberized grip is a great improvement over the Uniball One, which is all plastic, which may be great only for lettering, or precise writing or annotations. The zento ink is marvelous. The black is rich, dark, and also looks great. I will explore the blue ink as well. Coming from a Pentel EnergelX with needle tip, which i don't mind for cursive, this is far more confidence inspiring, in small part due to the 0.7 mm (*i had the 0.5 mm with pentel) but also the phenomenal ink, the precise nature of the flow of the roller-ball, and smooth feedback which is consistent from the page.

The Smoothest Writing Experience – A Workplace Essential
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.

The Perfect Glide: Uniball Zento Black Medium Point Gel Pens
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.

Smooth ink and sleek, minimalist design—perfect for planners!
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.
