Platinum #3776 Century Fountain Pen - Unkai (Limited Edition)
Introducing the newest of the #3776 Century Fuji Unkei series, “Unkai".
Platinum Penʼs flagship #3776 CENTURY inspired the “Fuji Five Lakes” (2011‒2016), created to commemorate its launch, followed by “Fuji Shunkei” (2017‒2021), which expressed Mt. Fujiʼs seasonal beauty through masterful engraving. In 2023, a new series was born: “Fuji Unkei.” Inspired by the scenery created by Mt. Fuji and the clouds drifting around it, the series combined the first bicolor design ever used on the #3776 CENTURY with intricate engraved detailing. As its final release, we are proud to present Unkai (“Sea of Clouds”).
For this concluding edition, we chose the magnificent sea of clouds surrounding Mt. Fuji as its motif. Layers of clouds spread silently into the distance as Fuji rises serenely above them. This ever-changing yet tranquil scene of majestic Japanese nature is captured in a single fountain pen.
Limited to just 1,500 pieces worldwide, "Unkai" is the final release in the Fuji Unkei series. This edition captures the delicate elegance of cirrus clouds with an intricate blend of guilloche and V-blade engraving on a translucent resin body.
For the cap and grip, colors were chosen to evoke Mt. Fujiʼs mountainside as it quietly reveals itself in the clear early mornings of autumn and winter, illuminated by the rising sun. On the barrel, lens-cut facets and carved grooves portray a sea of clouds spreading in layered formations, both delicately and dynamically. Changing with the light and the angle of view, its expression recalls a sea of clouds shimmering in the morning sun. Each time you hold the pen, the dreamlike landscape of Mt. Fuji rises vividly at your fingertips.
At the heart of this pen is a rhodium-plated 14K gold nib, offering Platinum’s signature smooth writing experience. The pen also features a domed finial with an engraved serial number, paying tribute to Mt. Fuji itself. To commemorate the release of the #3776 CENTURY Fuji Unkei Series “Unkai,” a special 20ml bottle of ink, “Fuji-no -Ebizome,” is included. The color is inspired by the moment when Mt. Fuji is veiled in the dim light of twilight, its slopes sinking into grape-red hues. As the light shifts, the lustrous reddish-purple gently softens, revealing a muted tone with a subtle green nuance. It evokes Mt. Fuji at dusk, whose expression changes with every passing moment.
As always, the pen includes Platinum’s patented Slip & Seal mechanism to keep your ink fresh for up to 24 months. Click here to shop all compatible Platinum ink cartridges.
