Description Pilot Iroshizuku Ku-jaku fountain pen ink is a deep, vibrant shade of teal green and comes as a 3ml sample in a plastic vial with a dip at the bottom to allow you to easily get every drop, labeled with the name of the ink brand and color. Iroshizuku Ku-jaku is inspired by the stark and vivid feathers of the richly multicolored peacock. Made in Japan, each Pilot Iroshizuku ink name derives from the expressions of beautiful Japanese natural landscapes and plants, all of which contribute to the depth of each individual hue.
