Left to right: 640, 740, 840, 940 and 141.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
The inks took 40 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
Bleeding: Low-there was some bleeding in the flex nib.
Other properties: 640, 740, 840 and 940 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.
640 is similar J Herbin Vert de Gris. 740 is close to Parker Penman Sapphire, but they aren’t an exact match. 840 is similar to Robert Oster School Blue. 940 is close to Colorverse Saturn V. 141 is similar to Birmingham Snowflake. Click here to see the Sailor inks together.
Life Bank paper brings out the undertones. 640 has a bit of a grey undertone.
I used a Bond Travel Gear A5 notebook. The inks all had a wetter flow.
Overall, all of them are nice, but 141 is too light for me in the smaller nib sizes. 740 is my favorite of these 5.
