Nakaya Dorsal Fin Version 1 Ama-iro
The Nakaya Dorsal Fin Version 1 is one of the most innovative and distinctive designs created by Nakaya. Layers of Urushi lacquer are applied over a period of months to create the fin on the cap, and the surface is then completed with either smooth Urushi or stone texture Ishime-Kanshitsu finish. With either finish, this is one of the most memorable writing instruments Nakaya has produced.
Just in time for those cloudless summer days, the Nakaya Dorsal Fin Version 1 fountain pen is finished in sky blue Urushi lacquer. The combination of playful blue with an expansive, angled shape sets this pen apart as a unique work of art and writing instrument. Multiple layers of urushi lacquer are applied over a period of months to create the raised cap fin - this is one of the most time-intensive procedures utilized by Nakaya.
As with all hand-made pens, colors will vary slightly from pen to pen - no two will ever be exactly alike.
Though the full range of Nakaya nibs is made available, the rhodium-plated version matches the cool, sleek tones of the Ama-iro finish.
