What a delightful and cool conversation starter. The Traveler's Brass Pen is a Japanese take on the vintage American “bullet” style pens. Hidden inside the glossy brass barrel is a pull out fountain pen that slides smoothly into place for sketching an idea, scribbling a list, or writing a love note. The Traveler's Brass Fountain Pen has a fine point and takes a standard fountain pen cartridge. Slide the Traveler's Brass Fountain Pen into your pocket, or attach it to your lanyard with the handy ring on top.
