Nakaya Dorsal Fin Version 2 Shobu
One of the most distinctive pen models created by Nakaya, the Dorsal Fin Version 2 is created by applying multiple layers of urushi lacquer over a period of months to create the fin shape on the cap and barrel.
With its deep purple color and smooth tamenuri finish, the Nakaya Dorsal Fin Version 2 Shobu fountain pen appears sleek and minimalistic. The unique double fin on the cap and barrel brings an angular dimension to this excellent writing instrument.


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.


14k nibs are well-suited to customizations including Stub, Cursive Italic, and Left Oblique, as well as the modification for added flex.
