These cufflinks feature a color combination of hematite, onyx and mother of pearl and are set it stainless steel. You'll never need to polish stainless steel because it'll never tarnish. Stainless steel is never poured into a mold like gold, silver or platinum; its hand cut from a solid piece of steel, so you'll never see a seam from a mold. Each cufflink measures approximately 3/4" x 1/2" and is hand finished to ensure you're getting the best possible quality. These cufflinks will go great with any color French cuff shirt or blouse. A perfect gift for that special man or woman on your list this year! Your cuff links will arrive in a handsome chrome presentation box which is perfect for gift giving.
