Sailor

Sailor is a Japanese maker of fountain, ballpoint, and rollerball pens. Their fountain pens take one of two proprietary profile ink cartridges or a proprietary piston converter. Their rollerball pens take a proprietary metal body refill of unknown length, while their ballpoint pens take one of two proprietary (similar to Sheaffer K style) refills or a standard D1 mini refill. If you know the length of their ink cartridges or rollerball refill, let us know.
