I quite agree with this comment. It's not the first time I see such "assertive" comments on Iroshizuku inks highlighting they aren't worth the price. Quite weird it comes from a moderator.....I've always replied to such assertive negative comments on Irohizuku inks that:
Go to the Ink Reviews forum and do a search on "Iroshizuku". For me, the most "different" of these inks is the slightly feminine Yama Budo.
Other than Yama Budo, none of mine really stand out enough to justify the cost of the ink, though they do make nice bottles.
And we made this man a moderator?
1) their overall performance in terms of flow and shading is generally better than most ( all , in my experience) inks . This already justifies the price in my opinion. All pens I filled with Iroshizuku inks write much better than before, but that's only my experience of course (although I've tried many inks in over 40 years....)
2) quite a few ( not all of course) of their colours are unique: for example, tsuki yo is a unique dark blue, Kon Peki a unique bright blue without needing to be a "south seas turquoise" , Fuyu Syogun is a marvelous bluish grey; Ku-Yaku is the most versatile blue/green on the market and can be used as an everyday ink; Yamaguri is a lovely dark brown ink, no too brown to be considered unusable as everyday ink, not too dark to be considered a desaturated black ink.
3) in general, in my opinion who is so negative on Iroshizuku inks either hasn't tried them thoroughly or...has a problem witjh his pens....
I am, by no means, an expert on inks. However, I will have to say this: Of the inks that I have tried, Iroshizuku's work in every pen, every time. Yes, there are cheaper products, but there comes a point in time at which performance matters more than cost. Sort of like buying a Kia Rio (or a "Sonic" that may or may not ship with working brakes) versus something else ;P
I cannot say that of the MB, Noodler's, DeA inks I've tried. Plus the Iroshizuku's seem to behave well in the pen, and most importantly ... stay in the pen and not on my hand.
Sometimes you just want something that works. Something that won't leave you looking like a smurf, or like you are supposed to be part of the "Blue Man Group."
I have tried samples of, or bought bottles(*) of: Shin-Kai; Asa-Gao*; Tsuyu-Kusa*; Aji-Sai; Kon-Peki; Take-Sumi; and Tsuki-Yo*. So far, they all seem well behaved, with Shin-Kai and Take-Sumi being rather "wet." Also, for the most part, they look like what they say they do. Only exception to that I've seen is Shin-Kai, which to me looks more like old fashioned "blued" steel than deep water. Not saying that I don't appreciate it, just saying that it wasn't quite what I was expecting.
