Very elegant Black and Gold glass buttons. 3/4" diameter. perfect condition. on original Jewel Tone card. 2 matched buttons. Made in Germany U S Zone. the thread that holds the buttons to the card is very delicate. when taking these photos one of the buttons came lose from the card. at least I was able to take a photo of the back of the button but was sorry it was no longer affixed to the card. the thread is there. single hole. beautiful buttons.I wish there were still 4 but the other 2 were used by the previous owner.
