Indestructible nibs show up around 1901 on souvenir pens from World’s Fairs and Expositions like the Pan-American Exposition (1901), the St. Louis World’s Fair (1904) and the Jamestown Exposition (1907). They are a gold colored metal and imprinted “Indestructible” sometimes they also include a manufacturers name. They’re nice flex writers which is why I started noticing them. They are not magnetic so they do not contain iron and I’ve never seen one with rust on it. They contain some copper as they displayed the characteristic green corrosion of copper after concentrated exposure to vinegar fumes. Beyond that don’t know what they’re made out of. Does anyone know what they are made of or more about their history?
