Kreisler Quality USA vintage cufflinks, ovals in goldtone with blue acrylic

This is a beautiful pair of vintage signed Kreisler Quality USA cufflinks in shiny goldtone with dark blue accents. The shape is oval with a little bit of a peak in the center. The semi-translucent acrylic blue accents are ribbed to look like baguettes. The cuff links measure 3/4” inches long by 1/2” inch wide. Signed Kreisler Quality USA on the backs. Also says 1/20 - 12KT G.F., so they may be gold filled. I didn’t test, so I am selling as goldtone metal. Very good pre-owned vintage condition.
