And the skulls just keep comin'! Here is the classic example of the skull and cross bones, perfect for those men in your life who are swashbuckling pirates at heart. These skulls are made of pewter silver, but are hollow to maintain their light weight. These are made in the USA by master pewter artisans, making each hand made pair unique. They feature a T-back for ease of wear, and they are conservative enough for everyday wear at the office. These cufflinks will arrive in a lovely gift box and they measure 1/2 inch x 1/2 inch.
