Italian-inspired mosaic fibre optic cufflinks set in a rhodium, silver mount. Conservative enough for the office, but far from boring. Unique design features both black and charcoal grey pieces of fibre optic cats eye glass fused together producing an eye-catching brilliance. coloured glass is meticulously combined to form a smooth pattern. These are an exceptional complement to blue, white, and many other French cuff shirts. Each pair is finished by hand to ensure a quality, lasting pair. Cats eye glass is made by fusing millions of fibre optic glass strands together, which creates glass that changes colour when seen under different lighting conditions. We have this style in other colours so please visit our store. They measure approximately 1.7cm in diameter. Nice heavy feel speaks to their quality.
