Pentel Sign Pen: The Japanese Invention That Reached the White House—and Space
Introduction: Have You Ever Used a Pentel Sign Pen?
If you’ve spent time in Japan or explored Japanese stationery, you’ve probably come across the Pentel Sign Pen. In Japan, it’s a household name—especially familiar to students, teachers, and anyone who’s visited a school. Known for its bright ink, it’s the go-to pen teachers use for grading papers.
But did you know this humble pen has a global story that stretches from American politics to outer space?
Let’s uncover the surprising international journey of this iconic Japanese writing tool.
The Birth of the Sign Pen in 1963
The Pentel Sign Pen was released in 1963 as the world’s first portable water-based felt-tip pen. At the time, most pens were oil-based and had major flaws—messy ink, bleed-through, and difficulty writing fine details.
Pentel’s new pen offered smooth writing, vivid color, and no smudging. It was a game-changer.
Yet, surprisingly, it wasn’t an instant hit in Japan.
Why America Changed Everything
Pentel believed the Sign Pen would succeed in a culture where signing documents was more common—like the United States. So they brought samples to the Chicago International Trade Fair.
Unfortunately, sales weren’t allowed at the event, so they handed out the pens for free.
One of those pens ended up with the White House Press Secretary. He passed it to President Lyndon B. Johnson, who tried it, loved it, and immediately placed an order for 24 dozen pens (288 pens) for official use.
This unexpected endorsement catapulted the Sign Pen to fame almost overnight.
From Presidential Desks to Outer Space
Thanks to its unique ink delivery system—based on capillary action—the Sign Pen can write even in zero gravity. This made it ideal for NASA missions, and it was eventually adopted as an official writing tool for space travel.
A pen that once struggled to sell in Japan had now reached the stars.
Global Success: 2.1 Billion Pens Sold in Over 100 Countries
Since its invention, over 2.1 billion Sign Pens have been sold worldwide. If you lined them up end to end, they would circle the Earth seven times.
The pen is now used not just for writing and marking, but for calligraphy, illustration, and professional design.
In fact, the international versions often have more color options than the Japanese ones, reflecting their popularity in creative fields abroad.
Try It Yourself: The Legendary Pentel Sign Pen
Whether you’re a journaling enthusiast, an artist, or just someone who appreciates great pens, the Pentel Sign Pen is worth a try. With its bold ink, smooth flow, and legendary story, it’s much more than just another marker.
Final Thoughts
The Pentel Sign Pen may look simple, but behind it lies a story of innovation, international recognition, and space-age technology. It’s a perfect symbol of how Japanese craftsmanship can resonate far beyond its borders.
Next time you pick up a pen, imagine it making its way from a Japanese classroom… all the way to the stars.
