uni-ball Zento Gel Ink Rollerball Pens, 4 Black Medium Point Smooth Writing Pens, Colored Japanese Pens, Muted Colors

I have never loved a pen enough to write a review. I'm obsessed with these! I've tried a lot of gel ink pens and while I have love for my eraseable frixions, for a comfortable nicely designed rollerball this is SO good. It writes very smooth with no skips and I find it very precise - when I write, there isn't any bleed of feathering I sometimes see with gel pens. The barrel is softer so it makes it more comfortable to hold and no smears so far. I definitely wish that there were more ink colors available, so hopefully that is on the way.

these pens are so good. smooth writing and dry quickly so my hand doesn't smudge. the design is very nice and sleek. the thickness of the pen is good for my hand to comfortably hold it. it's strong, pretty, and the ink is perfect and bold, writes down like i printed it.

Quality pens very functional smooth writing great value. Durable as well! You can never go wrong with any Uni-ball products.

Impressive quality look feel. Roller ball ink is fluid and dynamic. It’s a perfect pen. Rubberized feel and pleasant colors.

These pens are very pleasant to write with. The ink is very smooth. However, it's important to know that the 0.7 refills in these pens make a broader line than the 0.7 refills in the Pilot G2 and the ink is more fluid and is prone to bleeding through paper. The 0.5 and 0.38 refills are better for a wider variety of paper.

It’s a pretty good pen, officially a favorite of mine, an improvement in writing experience compared to Uni Ball’s One ink, less skipping and the flow is much nicer. Ink is less pigmented so it shows up as a dark gray and it dries slower than the One- especially on the all popular Tomoe River Paper. It’s like a more flexible & bleed resistant version of my favorite pen- the Zebra Sarasa Dry (also in 0.7mm). The shadowing on thinner paper (think 100gsm and lower) is pretty intense but a smaller tip will minimize this, go for 0.5mm if that’s a concern. The biggest flaw though? This pen completely rejects textured paper. I’ve never seen a gel pen feather so bad. The paper was only the lightly textured at that. Also haven’t seen any ink refills in this tip size sadly, only in 0.5 and 0.38mm sizes.

I’m in the medical field and good pens are a must! These pens are awesome! Everyone I work with uses them. They write so smooth and are comfortable in the hand! I will continue to purchase these!!

These are great pens! They write well and dry fast! They are just basic plastic but work well. They are a full size pen and come in great colors.
