This concho umbrella repousse button is slightly domed, made in the Four Corners area of nickel silver with a satin, barely shiny finish.  3/4" diameter, snap-on-and-off rivet on the back. Rivet holds snugly until you pull it off. And it's easy to snap back on, so you can easily remove and replace the button for cleaning.  $2.90 each
