This is the very height of fashion in the pre 1900's. A Sterling small mustache curler. This is like the old curlers that you put in the lamp chimney to get really hot and you curled your hair. This has a sterling handle and a Mother of Pearl button that you used to open the curler and heat the metal curler and then applied to your mustache. I think that you really had to careful or you would burn your lip! Such a neat little instrument It is marked sterling on both sides and the opener works fine. For you from the high plains of Kansas. We don't see many of these here!
