I believe these were purchased for a custom-made suit but were never used and have been kept. There are large ones and small ones (for sleeves). The center is a black velvet-like fabric. For those who enjoy sewing or are looking for replacement buttons, how about these? There is an engraving on the back, but I couldn't read it. They originally belonged to my super stylish mother, so I think they are of good quality. #sewing #buttons
