Pilot Iroshizuku Kosumosu is apparently Cosmos, which leaves me at something of a loss as to exactly what color the cosmos would be. As far as I know, the most accurate representation of that color would the Cosmic Latte, which is really more of a very bland brown that should really be called beige. Clearly this is not that particular hue. It is in fact a rather pastel pink that I believe would greatly please some of my more pinkly-inclined friends.
While pinks in general are not to my taste, this pink included, I must say that this particular color has me slightly puzzled. It is a pink that I would expect to have some golden sheen as is common to the red family, yet it has a slight shading and very so subtle gold sheen that I am unsure as to whether it qualifies as a sheening ink. For one, it definitely does not sheen with regular pen usage, and can only be forced out with larger ink volumes dispensed from a dip pen.
I cannot see this ink being used in a formal work setting, but it definitely is the kind of fun color that is relatively uncommon in fountain pen inks, which will result in this ink having its own niche. It is a slightly dry brew, with acceptable smudge resistance. It is not water resistant, which shouldn’t be surprising at this point.
Addendum: I was duly informed that Cosmos is not in fact a reference to the universe itself, but to Cosmos, the flower. Given its very distinctive pinkness, I am now inclined to agree that the Iroshizuku Kosumosu ink is indeed reminiscent of its muse. Shoutout to Meghan O’Connor from the Fountain Pen Network FB group for pointing this out.
