Nakaya Dorsal Fin Version 1 Ishime-Kanshitsu Midori
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.
The first Dorsal Fin pen created by Nakaya was the Version 1 in Ishime-Kanshitsu Midori, and it remains once of the most appealing examples of what has become a signature Nakaya style.
Successive layers of natural Urushi lacquer are applied over a series of months to create the distinctive fin shape, which also serves as a built-in roll stopper. The stone texture finish is then created with urushi powder. The pen body itself has been created from hand-turned ebonite hard rubber which is sustainably harvested from the rubber gum tree.
Nakaya pens can be filled with bottled ink using the provided converter, and can also use Platinum brand cartridges. Hand-painted Maki-e converters are also available.
