These distinctly unique cuff links are cast from my original anatomically correct heart design. The hearts each measure 7/8 inches long. They are cast in one piece of solid bronze including the rigid old style mounting hardware, no swivel pins, no solder joints, no glue. The hearts are not hollow, they are solid metal though and through so have a nice weight about them. PRODUCT DETAILS: AVAILABLE PENDANT METALS: Bronze SIZE: 7/8″ Length WEIGHT: 5 grams
