Today's ink is Sailor Jentle Waka-uguisu, "Young Nightingale" from the 2016 Four Seasons collection. Recently Sailor switched from 50ml bottles to 20ml bottles, but some retailers (like Pen Chalet) still have 50ml bottles left.
Waka-uguisu is a medium spring green. It's almost a green-yellow.
In large swabs there is some lovely shading.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 40 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper there was a little bit of feathering, and a tiny bit of bleeding, mostly in the flex nib.
I used a broad Pelikan M805 Ocean Swirl on Franklin-Christoph Sugar Cane paper, which does have a purple tone to it. The ink had a wetter flow.
Overall, Sailor inks flow really well, but it's not my favorite color green. Well behaved, just not an ink for me.
