Vintage rhinestone shoe clips

I originally bought these as an option for my wedding and ended up not using them. I found these at a high end flea market in Tulsa,Oklahoma. They are rhinestones set in a dark silver burnished metal and are most likely from the 1960’s. There is a small makers mark on the back left side that I can’t quite make out. This pair of shoe clips snaps snuggly onto the toe section of your favorite heels or flats to add a little extra bling!
