Platinum 3776 Century Koi Celluloid Fountain Pen

Platinum 3776 Century Koi Celluloid Fountain Pen

The Platinum 3776 Century Koi goes far beyond being a writing instrument; it is a living homage to Japanese artistry and craftsmanship. This fountain pen is made of celluloid, a traditional material admired for its warm touch and its subtle camphor scent, a result of its authentic manufacturing process. The vivid red-and-white patterns are reminiscent of the koi fish, a Japanese symbol of perseverance, courage, and good fortune, known for swimming upstream and overcoming waterfalls. This legacy of resilience and grace inspires a design meant to be treasured for a lifetime.

The celluloid is carefully cured for more than six months to achieve long-lasting stability and durability, ensuring every pen is truly unique. Inside, the Koi features a 14K gold nib polished by master craftsmen, including Platinum’s iconic heart-shaped breather hole. This traditional detail does more than decorate: it helps maintain a flexible, smooth ink flow and adds a special character to every stroke.

Care and maintenance

To protect and preserve this precious piece for many years, please follow these care tips:

• Avoid applying excessive pressure to the nib
• Do not drop the pen on hard surfaces
• Clean the nib gently with a soft, dry cloth (never use wet cloths, metal polish, or any chemicals)
• Soak the nib in lukewarm water about once a month to clear residual ink
• Change ink colors only after a thorough cleaning

Please also avoid exposing the pen to direct sunlight for long periods, as celluloid may fade or warp. Keep the pen away from open flames or heat sources since celluloid is highly flammable. Also, take care not to let the cap or barrel come into prolonged contact with ink, as this could cause stains or marks on the material.

If ink flow becomes inconsistent or if the pen has been unused for some time, soaking the nib for several hours in lukewarm water can help restore its performance.
