I have long ridden extremely hard for Muji's 0.38mm gel pens, which I used to have relatives in other countries send to me before Muji expanded into the US. But since I'm a sucker for an ultra-fine-tipped pen, I knew I had to try Sharpie's version, and now, I think I'm a convert. These write even more smoothly, no matter how I have the pen angled, and the gel is really black and doesn't smudge. Plus, since they're retractable, I no longer have to worry about losing all my pen caps at the bottom of my bag.
