Ikkaku by Nahvalur Ye-Yu Urushi Raden Fountain pen

Ye-Yu (夜羽), which directly translates to Nightly Feathers, is the first luxury fountain pen from Ikkaku by Nahvalur.

The rounded, cylindrical body profile is based on the Nahvalur Nautilus pen design with layered, deep black urushi and exquisitely inlaid raden that mimics the feathers of nightingales.

Each Ikkaku by Nahvalur Ye-Yu Urushi Raden Fountain pen arrives in beautiful wood box, and includes a Nahvalur converter. For maximum ink capacity, this pen can be converted to fill with an eyedropper by removing the converter and applying a small amount of silicone grease to the section threads.

"Ikkaku" is the Japanese word for narwhal and the mark of luxury expressed in urushi and raden. Ikkaku by Nahvalur is yet another testament to Nahvalur’s unwavering dedication to luxury writing instruments with high craftsmanship and artistry
