### ⭐⭐⭐⭐⭐ My Favorite Pens!
*by A***W on 17 December 2025*

When gel pens first appeared in the early 2000s, they were super unreliable. They'd stop, skip, make globs of ink. Even today I have trouble with the other brands that offer a lot of colors. So when I decided to try these I was a little wary, but they're excellent. They're extremely reliable, don't skip or gloop, and the ink doesn't really bleed the way gel pen ink used to either. I'm extremely picky about pens. Before this I used felt tip fineliners like Micron and Le Pen, which I like for their smoothness, but these are even smoother. They just glide across the page. I've tried to go back to felt tips and even fountain pens and can't bring myself to give up the feel of these. They're also just super comfortable to write with. The ink produces a beautiful line that stands out from the page, rather than seeping in the way ink from felt tips or fountain pens does. It's sharp, but not too fine. The point is just the right size for me. Anyway, I adore these. The only con for me is that the ink is not water resistant, so if you spill liquid on your notes it will bleed. If I really want something to be water resistant, I can use a boring Micron or a fountain pen with waterproof ink; but those just don't feel as good. Also: shoutout to Magenta, my favorite ink color.
