Platinum #3776 Century Fuji Unkei LE Series Unkai Fountain pen

Discover the Platinum #3776 Century Fuji Unkei Limited Edition “Unkai” Fountain Pen, the breathtaking final chapter in Platinum’s celebrated Fuji-themed collections. Limited to just 1,500 pieces worldwide, this exclusive fountain pen pays tribute to the magical beauty of the Unkai — the “Sea of Clouds” that surrounds Mount Fuji at sunrise, creating one of Japan’s most awe-inspiring natural landscapes.

Inspired by the Sea of Clouds Around Mount Fuji

The “Unkai” edition captures the tranquil and majestic scenery of Mount Fuji emerging above layers of drifting clouds illuminated by the rising sun. The cap and grip section reflect the warm colors that bathe the mountain during crisp autumn and winter mornings, while the faceted and intricately engraved barrel symbolizes the ever-changing movement of the cloud layers below.

As light interacts with the pen’s surface, the engraved patterns create shimmering reflections that evoke the sparkling beauty of a sea of clouds stretching across the horizon. The result is a writing instrument that beautifully translates a fleeting moment of Japanese nature into a timeless collector’s piece.

Distinctive Fuji Series Design

A signature feature of Platinum’s Fuji Series is the decorative dome finial, which houses a special nut representing Mount Fuji itself. This symbolic detail serves as the hallmark of the collection and is accompanied by the individually engraved serial number, emphasizing the exclusivity of each pen.

The Unkai edition concludes the prestigious Fuji Unkei Series, following the acclaimed Fuji Five Lakes and Fuji Shunkei collections, making it an essential addition for Platinum enthusiasts and fountain pen collectors worldwide.

Legendary Platinum #3776 Century Writing Performance

Built on the renowned Platinum #3776 Century platform, the Unkai combines artistic beauty with exceptional writing performance. The pen features Platinum’s acclaimed nib craftsmanship and the innovative Slip & Seal mechanism, designed to prevent ink from drying out, even after extended periods of non-use.

About Platinum 

In 1919 Shunichi Nakata started his fountain pen business, that would later be known as “Platinum Fountain Pen Co.” The Japanese brand is closely related to the legendary Nakaya fountain pen brand, where some of the finest fountain pens in the world are created. This expertise also goes into Platinum's own line of fine writing instruments.
