Description Pilot Iroshizuku Kon-peki fountain pen ink is a deep, vibrant shade of blue that is inspired by the color of a vast and clear summer sky. Pilot Iroshizuku inks are known to be smooth flowing and well behaved, and the 50ml glass bottle is cleverly designed 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.
