Esterbook began manufacturing nibs in the US in the mid 1800s, but the 1930s were monumental for them, as they introduced their first interchangeable nib system in 1933. The interchangeable nibs gave the user many options for writing, whether in school, business, or for personal use. Today, a similar system is reborn with the Estie and Esterbrook's specially engineered MV Nib Adaptor, which delivers a vintage nib experience with a modern shape Esterbrook pen.
