Italian-inspired square multi-colored cats eye cufflinks with silver finish. Custom design features a large handsome royal blue piece of cats eye glass in a beveled silver frame. All pairs are finished by hand to ensure a quality, lasting pair. Cats eye glass is made by fusing millions of fiber optic glass strands together, which creates glass that emits a brilliance when seen under different lighting conditions. They are absolutely beautiful! You will not find these for sale anywhere in the U.S. They measure approximately 5/8" x 5/8". Nice heavy feel speaks to their quality. Set in rhodium silver frame so it never needs polishing Covered by Cuff-Daddy's Lifetime product guarantee
