Pilot |IROSHIZUKU | Bottled ink for fountain pen | Wild Chestnut

Pilot Iroshizuku Bottled Ink – Wild Chestnut is a rich, earthy shade that captures the quiet elegance of autumn in Japan. Part of the acclaimed Iroshizuku (?????) ink series — named from the Japanese words “iro” (color) and “shizuku” (droplet) — this ink embodies the deep connection between language, nature, and the act of writing. Every ink in the Iroshizuku collection is inspired by a specific element of the Japanese landscape, and Wild Chestnut is no exception.

Known in Japanese as “Yama-guri” (??), which translates to “mountain chestnut,” this ink is a warm, deep brown with subtle red and golden undertones, echoing the hues of freshly fallen chestnuts scattered across forest floors. It's a color that evokes warmth, nostalgia, and the quiet stillness of late autumn days — perfect for reflective journaling, elegant note-taking, or creative writing that carries emotional depth.

The ink’s appearance varies slightly depending on the nib size and paper used. With fine nibs, it presents a classic, dark brown that’s professional and grounded. With broader or wetter nibs, subtle shading appears, revealing warm reddish-brown highlights and soft transitions that bring character and movement to the page.

Like all inks in the Iroshizuku series, Wild Chestnut is formulated for exceptional performance. It flows smoothly and evenly, delivering consistent lines with little to no feathering or bleed-through on quality fountain-pen-friendly paper. The ink is water-based and dye-based, making it easy to clean from pens and safe for long-term use across all fountain pen types.

Presented in a beautifully designed 50ml glass bottle, the ink reflects the refined aesthetics of Japanese craftsmanship. The bottle’s curved form and concave base not only make it visually stunning but also functionally smart — allowing users to draw ink easily even when the level is low.

Whether you're writing by a window on a quiet afternoon or journaling during a change of season, Pilot Iroshizuku Wild Chestnut brings warmth, depth, and a sense of connection to nature — transforming your everyday writing into something timeless and meaningful.
