ilot Iroshizuku Sui-gyoku fountain pen ink is a deep shade of green that is inspired by the deep green color of polished emeralds. Pilot Iroshizuku inks are known to be smooth flowing and well behaved, and the 50ml glass bottle is a cleverly designed bottle with an innovative dip at the bottom to make for easy filling of your fountain pen, when the ink level runs low.

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.
