Like all Sailor inks I've come across, this one is extremely well-behaved. The ink is smooth on the page, works great in the feed and nib system (meaning it starts quickly and doesn't skip or sputter), and dries really quickly on the page. In my unscientific tests, the ink is normally dry in under 15 seconds. And, as with all well-behaved inks, it's also easy to clean out of pens when it's time to swap in for something else.
The dark, subdued shade of this delicious green is something that makes me happy when I see it drying on the page. It's not a flashy ink, but it has a lot of hidden character that you can coax out with the right nib. It's dark enough to be appropriate in many business settings, but fun enough to use on a daily basis.
At $18 for a 20ml bottle, Sailor Ink Studio #960 is a bit on the pricey end of inks, but it does have a very unique story and some additional info on all 100 colors in the Color Studio line, as well as some blank cartridge converter labels so you can always remember what ink you have in a given pen. If this particular color doesn't strike your fancy, take a look at the other 99!
