It was replaced by a feather quill, then a steel-nibbed quill, a fountain pen, and finally the disposable Bic pen that was manufactured in the billions.

Designs went from balancing the glasses on your nose to tying them with a ribbon, holding them with a handle, and then finally using wire arms that hook behind the ears.
