Although the exact age and material are unknown, these are Art Deco vintage chain cufflinks from around the 1920s-30s, judging by the design and parts. They have a wonderful design that you don't see nowadays! The chain part has a brass-like color. Besides stabilizing the shape of the cuff, they also serve to prevent dirt and add decoration. Perfect for a stylish accent! Also great as a gift! Markings: None Please refer to the ruler in the photos for the size. I'm selling them after only dry wiping, as improper cleaning can cause uneven coloring. Enjoy the unique texture of these antiques. They are approximately 100 years old. There are minor scratches and signs of aging. Please refer to the photos for the condition, as there is some wear and tear. The last photo is a reference image from a contemporary advertisement.
