Kosumosu - Pilot Iroshizuku

April 12, 2015

In December 2007 Pilot's created exclusive line of inks called Iroshizuku. I believe they may well be the most well known fountain pen inks in pen world. These inks are supposed to work in any pen with any nib on any paper and in any situation. I haven't tried all of them but so far the Iroshizuku inks I've tried were behaving flawlessly.

The colors were created by Kiyomi Hasegawa who after fifteen years of working in a stationary shop and communicating with Clients come to conclusion that not all fountain pen users are willing to write in black and blue. Wise woman.

The bottles are stunning although they have their issues: if the ink is left unused for some time the cap tends to stick and break when you try to twist it open. It happened to my bottle of Shin-Ryoku.

Anyway Iroshizuku line of inks counts 24 "standard" colors. Three inks were made some time ago for Tokyo stores: Edo-Murasaki, Fukagawa-Nezu and Shimbashi-Iro.After seeing the scans over blogosphere I wish these three were accesible, because they look interesting. Edo - Murasaki looks cool while Murasaki - Shikibu is of no interest to me. Even though I kind of like Fuyu-Syogun I find Fukagawa-Nezu more compelling.

Nothing indicates Pilot plans on extending the official line any time soon (if ever) so let's take a look at what's possible to obtain from dealers and online shops.

I don't have all of the inks but sooner or later I'll try to check them all. With time I'll review all of them (hopefully).

I have this one. It is a very pretty pink. And sometimes you just need pink.

I never thought I would say this but I quite like this colour, probably enough to warrant a sample...

I'm loving the quality of these ink reviews! Thanks for the attention to detail.

Wonderful ink review. I love this color and don't have it, yet.

Thanks for the review. I always like these Iroshizuko reviews.

Thanks for this. I usually don't like pink inks, and I'll probably never use one. This one, however... reminds me of Coco Chanel and Audrey Hepburn. Kosumosu is just classy.

Sometimes my wife likes surprising me. She went to my B&M looking for Christmas items, and found some.

I've not had a pink ink since @ much of a decade ago, I gave a small cartridge box to Amber to pass on, Pelikan 4001 W.Germany cartridges. I now have Iroshizuku Kosumosu.

I am very happy from the reviews it shades well. That old Pelikan didn't , or didn't shade well enough to have kept it.

There is some sort of brown discontinued Iroshizuku ink, that I have hopes of getting.....even if at €29 it is 9 over my limit.
