These are really stunning unique cufflinks. They are inspired by Italian design and have two layers of fiber optic cat's eye glass set in a rhodium silver setting. This creates a beautiful shimmering blue design. The silver setting will never tarnish, need polished and will remain shiny. These cufflinks will look stunning in any setting, work or formal, and with any color of shirt. These cufflinks will arrive in a nice chrome box and are a perfect gift for groomsmen. These are heavy, substantial cufflinks and are finished by hand to ensure high quality standards. These cuff links measure 3/4' x 5/8'.
