Kate Spade sunglasses with green leather case vtg good condition made in Italy

vintage Kate Spade sunglasses with leather green case made in Italy. I could not find this specific model anywhere on the Internet, and the inside of the frames have the letters K & S on them, so didn't have a guideline to price it, other than the fact that these are very rare. there are a couple nicks on the leather case but the inside is pristine.
