My FAVORITE pens!
These are my favorite pens. Not only are they cute but they actually work well. Ever since I found these, they have been my go to. The ink is nice and dark and they write really nicely. It’s comfortable to hold, my hands tend to get clammy at times but I can still get a nice grip. I gifted some to my coworkers bc they liked them so much and were always asking to use mine. One of my students even wanted to earn as a reward because he liked it so much and said they’re also great for drawing. It can smudge a bit but typically dries quickly. I highly recommend them.

I didn't know I could HAVE a favorite pen. This is my favorite pen.
I bought these to put on my wedding guest book table. Sure they're a little pricier than BiC, but they matched my color scheme and I was feeling manic planning all my decor. I did not expect them to be my new favorite pens. Well, they are. They're perfect. They're lightweight without feeling cheap. They write clean and smooth and dry instantly. They are cute to look at. They have a slight rubbery texture which is good for my grip without causing any blistering (I have sensitive skin) and also doesn't seem like it will wear away over time. I love them. I have them all over my house now that my wedding is over and I'm so happy about it. I can't recommend these enough. 10/10.

Awesome pens
Love love love these pens, they have a matte feel and are very cute colors. Writes like gliding and the point is thin.

These Pens have that je ne sais quoi.
I’ll start by saying I’m not a fan of rubberized gripping sections. I think that it is largely due to undesirable experiences with them over the years. For example: Sections that actually felt slippery, I guess due to skin oil buildup over time. Sections that became dust and grit magnets. Sections that threw the overall balance of the pen off because they were a separate slip on piece added to the pen barrel (and over time also developed the aforementioned issues). Not so with the Uni-ball Zento Gel Ink rollerballs! The weight of the pen is very light (perhaps a little too late IMHO). Of course the lightweight lens to the possibility of Long writing sessions. I love the assorted barrel colors and the fact that the pen body is one color. Although the pen is very light, it somehow feels sturdy and very well-made. If someone asked to borrow my pen I could confidently give them one of my Zento’s and not cringe if they happen, heavy-handed bearing down on my pen as they write. These pens are even safe from those borrowers who love to slide their thumbnails under the pocket clip. The Uni-ball Zento has a spring loaded pocket clip. A very nice feature, unusual for pens in this price category. However, Uni-ball also offers it in their ”One” series. Another subtly excellent feature is the name and point size of the pen discreetly stamped on the body. The pen barrel is a comfortable size. Just the right width that would fit nicely in the hands of most people. The ink flows very nicely on the page and (very important to lefties) dries very quickly. There is very little if any smearing. Suffice to say I like these pens. I hope they become more widely available.

Left handed friendly !
Very comfortable in the hand, you can tell this is pen of the year for a reason with its amazing quality for the best value. One of the smoothest writing experiences I’ve had, the grip is so stress free even with long stretches of writing. And the ink drys fast which I can appreciate as a left handed person who grew up with pen and ink smears on his hand

Great pen
I write alot at work and Im very particular about my pens.I was hesitant buying these at first because the pen doesn't look like it has a gripper at the bottom for your hands.They fit perfect in your hand and are very smooth.They write smooth also. I like that the clip opens so you can attach it to your scrubs tops or pants.I will definitely be buying more!!

Smooth Writing but Ink Could Be Darker
The pens write smoothly and provide a great writing experience, but the ink isn’t as bold or dark as I’m used to. The retractable 0.7mm medium tip delivers ultra-smooth strokes and the quick-drying gel ink prevents smearing. I like the sleek design, soft grip, and eco-friendly materials. The spring-loaded clip is practical, and the barrel colors are stylish and calming. Overall, a good pen, but the ink could be a bit darker.

Comfortable grip, smooth writing, no smudge!
I am a huuuuge pen snob! I work in the medical field & pens are very important. These are by far my favorite pens I have ever ever purchased! I will buy them again! I doodled on a sticky note and gave it to my boyfriend. He stuck it to his mini redbull fridge, which has a lot of condensation on the outside. The sticky note is been soaked multiple different times and the ink has not budged at all! It’s so impressive!

Havia lido algumas resenhas sobre estas canetas, eleitas como as melhores de 2024 por jovens escritores pela escrita macia, sem falhas e tinta que não vaza para o verso da página. Quando chegaram, testei e realmente me surpreendi. Melhor caneta que já usei.

Smooth writing, love the colours of the pen (ink is black)

Gran precio, gran calidad. Probablemente el mejor producto de Unibal. El clip es fantástico y muy conveniente. El mecanismo retráctil es más práctico que la tapa removible. La tinta fluye sin interrupciones y el tono es bastante oscuro. Hasta el momento no he tenido problemas con el sangrado. Anexo una fotografía comparando la escritura con otras marcas competidoras, incluido el reverso para que comparen el sangrado. (Disculpen mi letra.)
