This listing is for ONE (1) enameled butterfly. There are 12 available.
The metal appears to be copper, but I don't know if they are solid copper or copper finished. They are non-magnetic metal and I don't see any place that indicates they are copper covered. There are three (3) colors of enamel - light coral, green and a deep periwinkle blue. Really pretty.
They measure 1 & 3/16" (30.16mm) by 1" (25.4mm), including the loops. They are in excellent, never used condition. There are so many possiblilities for how these could be used - all that's needed is your imagination.
