Blazer Suit Jacket Buttons Set of 13 gunmetal tone crests lightweight

Set of 13 total buttons. 7 are the larger 1” size and 6 are the smaller 3/4” size. They all match and came off a lovely ladies blazer jacket. They are a tarnished silver or gunmetal tone. They are very lightweight, I’m not sure what they are made of. Please see the listing pictures for details and measurements. Thank you for shopping my items, I’m happy to answer your questions(:
