Pilot Iroshizuku Take-sumi (bamboo charcoal) 50ml

Pilot Iroshizuku Take-sumi is a deep, elegant black fountain pen ink inspired by the quiet richness of bamboo charcoal. Smooth-flowing and well-balanced, it delivers strong saturation with a subtle warmth that keeps the black from feeling flat or harsh. In the 50 ml glass bottle, Take-sumi is a refined everyday ink—clean, professional, and effortlessly expressive on the page.
