This is a set of 6 bottles of Yama-budo (wild grape) ink. ■ These are the much-anticipated mini bottles (15ml). They can be used not only with fountain pens, but also with glass pens and dip pens. ■ "Iroshizuku" is bottled ink specifically for fountain pens. Japan has many beautiful natural landscapes and scenery, and they also have very beautiful names. The iroshizuku-色彩雫 (iroshizuku) series is a collection of richly colored inks created from those beautiful scenes. Attach a separately sold converter, dip the nib up to the neck in the ink, and use it by the respective filling method (lever-filler, twist-filler, or push-filler). * For plunger-type fountain pens, fill directly into the pen body.
