Pilot Iroshizuku - Hotaru-bi (Firefly Light)

Pilot Iroshizuku Hotaru-bi (蛍火, "Firefly Light") evokes the flicker of fireflies over a summer field — a lively, luminous grass-green ink with soft yellow undertones. Shading is high, moving from gentle spring green to deep, vibrant tones, giving handwriting real dimension without any sheen or shimmer to distract from the base color. Flow is smooth and juicy on the page. Fountain pen safe across all nib sizes.

The Iroshizuku name comes from iro ("color") and shizuku ("droplet"), and each ink is named for a Japanese natural landscape or plant.
