The Platinum #55 Karakusa Blue Celluloid fountain pen features a hand-engraved chinkin pattern on a celluloid body with rhodium-plated trim. It is made available with your choice of 14k solid gold rhodium-plated Century nib.


Celluloid is one of the classic materials for quality fountain pens, and Platinum as always offers tremendous value - comparable pens using the same materials and engraving techniques could well be priced at two or three times as much.

This is a durable and well-designed cartridge-converter pen. It can be filled with bottled ink using the provided converter, or with Platinum brand cartridges. It can also utilize Nakaya's hand-painted Maki-e converters.


The time-intensive process involved in producing the Karakusa Blue Celluloid begins with curing the celluloid. Afterwards, the delicate floral pattern is hand engraved from top to bottom using the Chinkin technique, in which a sharp instrument is used to cut the fine, narrow lines of a motif onto a lacquered surface. The lines are then filled in with metallic powder. Even the section features the silver colored design.

Platinum's "Slip and Seal" cap system is designed to keep ink fresh and the pen ready to write. The rhodium-plated clip is sleek and functional, allowing you to affix this mid-size writer to a shirt pocket.

These 14k Platinum nibs are well-suited to customizations including Stub, Cursive Italic, or Left Oblique, as well as the modification for added flex - see our nib customizations page for more information.


The Platinum #55 Karakusa Blue Celluloid fountain pen arrives in an elegant presentation box and includes converter and a starter ink cartridge.
