Measures about .75" across or about 19mm. Shows minor signs of cosmetic wear, plating wearing off on parts, nicks, etc. Harvested from a vintage wool Salvatore Ferragamo jacket. I have several and tried to photograph the one in the worst condition. The look better in person than the photographs. Message us with any questions or concerns!
