A 2ml sample of Pilot Iroshizuku Hotaru-bi chartreuse green fountain pen ink, in a labeled plastic vial.
Hotaru-bi (蛍火), translated as Light of Fireflies, is inspired by the soft, light of delicate fireflies. This color is a bright chartreuse green with warm yellow hues.
The name Iroshizuku is a combination of the Japanese words Iro; 色彩 (Coloring), expressing high standards and variation of colors, and Shizuku; 雫 (Droplet), that embodies the very image of dripping water. These gorgeous Iroshizuku inks have been inspired by beautiful Japanese environments. Each ink name derives from the expressions of beautiful Japanese natural landscapes and plants, all of which contribute to the depth of each innavidual hue.
