Left to right: 564, 664, 764, 864 and 964.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
The inks took 20-30 seconds to dry.
Water resistance: Low
Feathering: Low-there was just a little bit of feathering in the flex nib on Rhodia and Leuchtturm.
Show through: Medium
Other properties: 664, 764, 864 and 964 had medium sheen. All five had medium shading.
On Staples 24 lb copy paper there was lots of feathering in the larger nib sizes as well as a bit of bleeding.
564 is similar to Birmingham Emerald Scout, 664 is close to Pilot Iroshizuku Ku-jaku. 764 is similar to Robert Oster Morning Mist. 864 is close to Colorverse Pale Blue Dot. 964 is similar to Robert Oster Deep Sea. Click here to see the Sailor inks together.
Life Bank paper brings out the undertones. All five of these lean more toward green than blue.
I used a Bond Travel Gear A5 notebook. The inks all had a wetter flow.
Overall, like all 5 of these. The color really depends on the paper you use, on some papers they look more blue, on some they look more green.
