And now to perhaps one of the most famous of the Iroshizuku inks, Tsuki-yo. Well at least famous here on FPN for KaB's "most boring" thread. If you haven't checked it out, you should.
Pen: Edison Premiere (F-Steel)
Papers: MvL=Mohawk via Linen, Hij=Hammermill 28 lb inkjet, TR=Tomoe River.
Tsuki-yo is not as saturated as the Iroshizuku Asa-gao, or it's favorite competitor Pelikan Edelstein Tanzanite. But is has very good qualities: shading on nearly everything and sheen on less absorbent papers such as TR. You could say it's quite inoffensive in its blue-blackness, but in a way that is also it's charm. It would work in every school or business environment. And for one's own writing it is reliable and readily available. If you like brilliant colors, and retina-searing inks, Tsuki-yo is not for you, at least if it is your choice in ink.
