Although the exact age and materials are unknown, these are vintage Art Deco double cuff links from around the 1920s-30s, judging by the design and parts. A wonderful design not found in current products! In addition to stabilizing the shape of the cuff, they also serve to prevent soiling and as decoration. A great accent for your style! Also makes a great gift! Markings: None Please refer to the ruler in the photos for the size. I'm only wiping them with a dry cloth to avoid uneven coloring if I clean them improperly.
