About this ink:
This is a special or seasonal ink made by Sailor for Bung Box. The name of the ink can be broken down as:
Tsuyu つゆ= dewdrop
Hikari ひかり=light, shine
So in my head I read it as Light shining on a dew drop. It matches a local tea, "Tsuyuhikari つゆひかり is a variety of a green tea plant that is grown in Omaezaki, Shizuoka-prefecture in Japan," according to my friend and colleague, Jesse (aka PenJockey.) Rumor has it if you request to sample this ink at Bung Box, they will brew you a cup of tea that perfectly matches this ink.
TESTING: Although I am generally not a fan of Green inks, I found this ink intriguing. It goes down as a light -- almost neon or bright lime green -- and begins to change almost instantly. It picks up strong olive green and light gold brown tones, almost dusky notes. Only in the Swab do you see it stay the same color as what is in the bottle.
The ink is quite wet, even in my dry 15 year-old Namiki Vanishing Point pen (F). I found it shaded nicely from light green to a deeper green. It takes roughly 7-8 seconds to be smear proof. As I wrote I noticed some sections of my writing were lighter and some were more of a light olive green.
There is shading, from light to a medium tone.
Paper used was HP 32 pound Prem. Laser.
I submit only a full scan as the camera kept moving toward blue.
