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

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

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.

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

Felt good in hand for writing comfortable

Nice and smooth

They do not smear! Definitely will try the more premium version of this pen once it is in stock based on this cheaper version. The ink dries instantly and the pastel colors allow them to be located quickly on my desk.
