Left to right: 931, 237, 437, 737, and 135.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
The inks took 15-20 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: 931, 437 and 737 have medium sheen. All five inks have 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.
931 is similar to Monteverde Gratitude. 237 is similar to Kingdom Note Mycena Pura. 437 is similar to Platinum Lavender Black. 737 is closest to Bungubox Sweet Potato Purple. 135 is similar to PenBBS Wistteria Sinesis. Click here to see the Sailor inks together.
Life Bank paper brings out the undertones. 237 has a surprising greenish brown undertone, 437 leans a bit brown, and 135 has a bit of blue.
I used a Bond Travel Gear A5 notebook. The inks all had a wetter flow.
Overall, I like all of them, but none of them are super unique, so I’m ok without full bottles.
