Ringtop fountain pens were common for only a very short period of time, from the 1900s up until the end of the 1920s and they were marketed (and manufactured) for both men and women. It’s easy to tell the difference between men’s and women’s pens purely from their lengths. Women’s pens were longer (four inches or more); they were worn with a chain or a ribbon around the neck, like a necklace. Men’s ringtop pens are significantly smaller, generally being no longer than about three and a half inches.
