Together with thongs, horn toggles are a form of a button really and were used predominantly on medieval shoes (especially Viking origin) and seem to be used in the northern more primitive cultures. Mysteriously they seem to almost disappear (apart from toggle like ornaments used on Tudor garments) for centuries from the high fashion, with toggles on shoes being discarded buckles, lacing and buttons being used in later centuries. These toggles have been hand polished with each toggle having two pre-drilled holes. They come made of two toned horn. You can use these on period, cloaks, shirts, or shoes to give your costume an authentic look.
