Love these pens!
I didn't think I would like these due to the shape, but they are actually really comfortable to use! They write amazingly. I am a pen snob (I could actually sell my pens to Amazon for years to come I'm sure) so I'm very picky. They have never skipped on me and work amazingly in all of my TRP planners and journals. They last forever it seems. Lightweight. Fits perfectly in my hand. And they come in some of the cutest colors!!

Great feel
I like a heavier weight pen and this is perfect for filling out my weekly planner. Shaky hands makes my handwriting tough to decipher but the weight and tip of this pen help some.

Favorite pens
This is my new brand of pens that I am obsessed with the only thing I don’t love about it is that it randomly goes out on me, but then comes right back.

Garbage
All 4 pens came with damaged tips. The ink cartridge gets jammed when you try to click the pen because of the damage. Don’t waste your money with this seller.

getting better and better
I did not imagine that Uniball can come up with anything better than Signo 0.38, but these one F are amazing! so smooth! have a little weight, so they are easier to hold. Fine writing.
