Antique Art Deco Hadley Cufflinks & Shirt Studs Tuxedo Set in Original Box

This is a beautiful Art Deco tuxedo set made by Hadley in the U.S.A. with the original box. The gold-tone cufflinks and studs have a beveled design and are made of purple abalone or mother of pearl shell. The cufflinks have been used and have some stubborn residue on them. There is some tarnish on the backs of the shirt studs. The box still has a sticker on the lid that lists these as "Set 235." The box feels like cardboard and has velvet holder for the jewelry. Overall, the set is still in very good shape for being made sometime around the 1920s or 1930s. *The cufflinks were loose, and I have tied them down with some sturdy quilting thread. Approximate Box Dimensions: 4in x 2.75in x 1in
