WORST PEN EVER
These pens literally fell apart in our hands. Total waste of money unless you're inclined to tape them back together. The entire box did the same.

Fall Apart Quickly
I loved these pens at first. But in just a few months the pens started falling apart as I was writing. I've already had to throw away most of them. They would just come apart in my hand! (More are in the trash now than what I have left.)

Pen Leaks
The pen is good at first but after a week of using it it leaks and blobs on paper. If it did not leak I would have rated it a 5 star.

Pentel liquid gel pen
The EnerGel pen has a smooth glide and quick dry ink. It's just what I expected.

Great Pen
This pen is a little larger to grip and that works better for me. Also it is a smooth pen as it works its way across the page.

my favorite pens (great for lefties!)
I’ve been using these pens for a few years and love them so much. A bit pricey but they last a very long time.They have really unusual colors and they are so pretty. They’re also smear proof and very good for lefties. :)

Best pens ever
These pens are quite literally the best pens that I have ever used. They glide so smoothly across the paper. It feels like I am using a fountain pen. They do not smudge and dry very quickly. I would recommend these pens to anybody who is in school and takes a lot of notes or anybody who just likes a good quality writing material in general.
