Although the exact age and materials are unknown, these are vintage cufflinks that appear to be from around the 1940s-1950s based on their design and materials. Besides stabilizing the shape of the cuffs, they also serve to prevent soiling and add decoration. Perfect as a fashion accent! Also great as a gift!
