Beautiful little star-flower surrounded by leaves. Highest quality, very domed, rounded-top metal button. A bit of sheen but not too-too shiny.  Etched metal is dimensional , the edges are black or nearly black, and the button looks antique. They are about 7/16" thick including the shank, with a 2.5mm opening.  

This is for the smaller size, 11/16", in Copper. (We also have it larger, and also in silver in two sizes.  All are listed separately.)  Priced $2.20 per button.
