This is a set of 11 buttons that I believe may be glass. Shank style. Black faceted and rounded top. There are 10 that are 14 mm across and match. Then there is one matching large one that is 19 mm across. I purchased these in a huge lot with other Victorian era buttons, so I assume these are from the same era. They are in excellent condition for their age - a few little nicks on some of them but no major chips.
Beautiful buttons and quick shipping. Perfect for the bodice I'm making. Thanks!
