I love these brass buttons and they way they look. I domed these 25mm buttons and added two holes. The copper content in the brass is pulled to the surface and is left, along with some black oxidation, as the surface color. The holes and outer edge of the button is polished so the brass shows through to highlight them. Each one is unique and different. You will be getting them similar to what you see in the images. I finish them off by using a lacquer coding to protect the finish. You can order these with a smooth surface or hammer textured surface.
Let me know if you have any questions. thanks, for looking
