The Ohto pen company was founded in Tokyo in 1919. It is one of the great old pen manufacturing companies in Japan, and was the first Japanese ballpoint pen manufacturer. They have since made many memorable contributions to the world of writing instruments, including the distinguished Horizon ballpoint pen we carry. Which brings us to the wonderful Dude Fountain Pen, which I used to write the first draft of this paragraph. As you can see, this pen is ultra smooth and wonderful to write with. The body is an artful hexagon with a rubber grip, cool to look at and comfortable to hold. We carry refills in blue and black.
