Platinum Biso Sparkle Mint Green GT Fountain pen

Introducing the Platinum Biso Fountain Pen, a writing instrument designed to inspire calm, clarity, and self-expression. The name “Biso” combines the Japanese characters for beauty (美) and harmony (奏)—a reflection of the pen’s purpose: to help you write beautifully and with inner balance.

Crafted with a lightweight, slim-profile body made from pearlescent resin, the Biso fountain pen offers a gentle shimmer that shifts subtly with light and angle, adding elegance to every writing moment. Compared to the Platinum #3776 Century, the Biso is noticeably lighter and slimmer, making it ideal for longer writing sessions and everyday comfort.

Finished with a gold-plated stainless steel nib, the Biso delivers smooth ink flow and a refined writing experience—perfect for journaling, letter writing, or personal reflection.

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.
