Most impressive buttons we ever owned, three huge button of a semi-shiny black material, not glass but looks like it, on which is applied with tiny silver nails a fabulous silver tone metal filigree circle, with the entire button framed in silver tone metal as well with designs on that also. Original loop still on the button backs. We have three and each button measures 2 & 1/4" across and all are in very good condition. We have not cleaned or tried to polish these buttons at all. Price is for 1 (one) button. We have never seen any other like this so large and so ornate in a long time.
