Uni-BallZento Gel Ink Rollerball Pens, 4 Black Medium Point Smooth Writing Pens, Colored Japanese Pens, Muted Colors

Very nice pens. For the pen enthusiast, give these a try. They write well, look cool and have and have an interesting designz the clip is unique and reminds me of a paper clip. Quality is high for the cost and the writing experience is good. No issues with the pens leaking and they are comfortable to write with.

My absolute fav pen! The ink is juicy, it doesn’t usually smudge for me. I love that the pen feels like silicon so it doesn’t slip out of your hand when writing. I could write with this pen for hours!!

So these are a neat design. The click is nice. The wire clip is excellent with a sort of spring pivot. The colors are nice. The thickness of the pens and ergonomic round shape is great. The ink is bold, comes out well, and provides a fairly smooth writing experience. One interesting thing is that instead of having a rubbery grip section just near the tip, this section is most of the pen. For sensitive customers, this type of material can feel a little icky at first to some people but that effect wears off once they are used a bit and exposed to natural finger oils.

I love these pens! I love that you can buy refills as well, although I am not sure if I have the motivation for that.

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 love the uniball pens, this zento are nice, writing it's soft, the black ink it's not saturated, but it's ok.

They feel comfortable on the hand and the writing is very good.

These pens are excellent. The ink flows well and is a definitive black. They don’t bleed through the paper!
