Human Skull Cuff Links – Solid Bronze Skull Bone AccessoriesThese precisely carved half skull cuff links are made of solid bronze with an ancient oxidized finish that reveals every tiny detail. The skulls are just the right size, each measuring 7 8" long by 5 8". They are cast in one piece including the rigid old style mounting hardware, no swivel pins, no solder joints, no glue. The skulls are not hollow, they are solid metal through and through so have a nice weight about them and will last several lifetimes.
