Review: best pens ever - These write very smooth and last a decent amount of time! I also like the simple design
Review: Amazing - These are some of the best pens I’ve ever used. It’s crazy because I bought the ones with tops a couple of years ago and didn’t love them, but these retractable ones are so much better. Almost everyone who uses one immediately wants to know what kind they are and where they can order them. They also dry very quickly and do not smear in my journal. Love them!

### ⭐⭐⭐⭐⭐ best pens ever

### ⭐⭐⭐⭐⭐ Amazing
*by L***Y on January 10, 2026*

These are some of the best pens I’ve ever used. It’s crazy because I bought the ones with tops a couple of years ago and didn’t love them, but these retractable ones are so much better.

### ⭐⭐⭐⭐⭐ The modern Bic ballpoint that writes like a rollerball.
*by M***L on January 21, 2026*

These are great. Ballpoint 0.5mm gel write like rollerball, but no smudging. Stiff body - only lacks grip cushion. Front unscrews for service of cartridge and spring. Positive extend/retract action. I've tossed that dozen or two ballpoints and rollerballs I've accumulated and replaced them all with these.
