Description Pilot Iroshizuku Ajisai fountain pen ink is a gorgeous shade of bright blue 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 Ajisai is inspired by raindrops on hydrangea petals. 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.
