Endless Alchemy Fountain Pen Ink - Obsidian Moon

HK$165.00 HKD


The Moon, bottled.
Obsidian Moon captures the stillness of midnight with the moon — a deep black ink kissed with silver sheen and shimmer, like starlight glinting on quiet water. Every stroke shifts between shadow and light, adding depth to words that deserve gravity and brilliance.

Formulated to be fountain-pen friendly, Obsidian Moon flows smoothly, dries reliably, and leaves behind an otherworldly glow. For writing that feels timeless.

  • The ink is formulated to be gentle on nibs, preserving the delicate components of your fountain pen and extending its lifespan.
  • Suitable for Fountain Pens, & Dip Pens.
  • Periodically flush your fountain pen with clean water to remove residual ink.

45ml unique bottle with recessed bottom to allow for getting each last drop of ink. Cork base to hold bottle level when filling.
