Although the exact age and materials are unknown, these are vintage chain cufflinks with an Art Deco design from around the 1920s-30s. A wonderful design not found in current products! In addition to stabilizing the shape of the cuff, they also serve to prevent dirt and add decoration. Perfect as a fashion accent! Also great as a gift!
