Sleek 925 sterling silver only represents one highlight of the Sterling Silver Skull Crossbone Cufflinks. The other highlight sits prominently at the end of the mount. These cufflinks expand on our Sterling Silver Skull Cufflinks by adding the iconic crossbone. Feather black enamel also creates a unique design not matched by any other pair of cufflinks. You can wear these cufflinks with a costume for Halloween or year round attached to your favorite dress shirt.
