Writing
As every Sailor pen I've tried before it, it writes beautifully and effortlessly. It's a fine nib (no other options available here), and it runs finer than other Japanese nibs, like Pilot or Platinum. It's almost too fine for my taste, but it isn't an issue because it writes so smoothly.
This wasn't always the case, however. When I got the pen, it was a really dry writer. It wasn't unusable, and some might even prefer how it wrote out of the box, but I lean toward wetter nibs all around. A couple of gentle pulls on the tines to bring them away from the feed a bit fixed the problem for the most part. At some point I might like to have it worked on by a professional, but it writes great now.
It's the kind of fountain pen nib that I'm 100% confident about. Know what I mean? It's had zero issues with starting, skipping, drying, or any of these problems that sometimes plague or briefly affect pens. Some of my pens have 95% of my confidence, because every now and then they might skip or have a hard time starting, and they always respond to the same fixes. They write well, but sometimes have a small little issue. Not this one. It's a great writer.
It also feels great in the hand, as you might expect from Sailor. It's well balanced in the hand when writing and feels like an extension of your hand instead of a separate object.
