These are pretty amazing vintage Czech buttons. They are black glass with a flower design molded into the top, intaglio style. There is extraordinary detail to these flowers, and also really lovely fancy scalloping around the edge of the button. The black tops are flat and polished and the flower and edges are finished with a silvery coating. These buttons have glass shanks and measure 22mm or about 7/8 inch in diameter. These buttons are coming directly out of the original wraps to you, and they were also packed in cotton, and even so you may see some small dings in the back edges of a few of these buttons.
