First we started with a block of stainless steel. Next the 316 stainless steel is cut with precision to leave voids. After that the natural semi-precious abalone and rich, hard coat enamel are added. After these are finished by hand, the result is a durable, unique set of designer cufflinks that will last a lifetime. This set of cuff links comes in a beautiful chrome gift box. Made from rhodium silver so they'll never tarnish. Coveredy by Cuff-Daddy's Lifetime product guarantee
