Uniball Zento Gel Ink Rollerball Pens, 12 Black Medium Point Smooth Writing Pens, Colored Japanese Pens, Zen Colors

If i could give these 100 stars i would!!!! I don't usually write good reviews ngl. But these 100% warranted one. I've been writing with the same single pen out of this box for 30 straight days. And i do A LOT of handwriting as a grad student and small biz owner. Never ONCE did that pen skip on the paper, it was always fluid and the lines were always crisp. This one single pen just now ran out of ink 30 days from when i opened the box, 10 seconds before i came here to write this. Im used to Uniball being excellent. I usually swear by their pilot pens. But these make me never need to buy any other pen ever again. The "ergonomic" and "organic" design is a little iffy to the touch at first but you definitely get used to it. 10/10 will recommend to everyone. And the price is incredible. This is basically a year's supply of pens for less than $10

Really smooth

These pens are the some of the most well-designed writing instruments I've ever used.

These are the best pens I have ever owned. The ink is strong a doesn’t bleed or smear. Writing is smooth. 4 stars because the colors are misleading - I did not receive all of the colors.

Great pens, liked using them and will be buying more

This is a neutral review.These pens have a lovely look and feel to them. I love the grippy-soft sensation while holding them.They are solidly built. The button is easy to use and feels like it will hold up. The clip is a lovely design and grips really well. It feels strong and seems like it will hold up.The ink glides on the paper slippery fast when writing. Almost too fast for me. I have noticed significant bleed-through on notebook paper, particularly when printing or overwriting to fix something. Pausing with the pen on the paper will cause the ink to go through to the other side in a second.Despite having these within reach, I find myself using other options. My cursive gets really messy because of the seemingly total lack of resistance, and the ink comes out too much when I print.To restate - I love the look of them. The build quality is great. They feel wonderful to the touch. Unfortunately, they do not meet my writing preferences.These may be just the thing for other folks.

Great product

Best writing experience I've found.
