Product Insights
Le 31's Circular Onyx Cufflinks blend practical engineering with genuine materials: a hinged swivel back enables one-handed fastening with a tactile lock that surpasses bullet backs in security, while the 2 cm post clears thick double-cuff fabrics without jamming. The genuine onyx stone offers a cool-to-touch feel and subtle natural banding, but is chip-prone and dyed, requiring careful storage in the included lined box and gentle cleaning. Backed by Simons' private label since 1991, designed in Canada, these cufflinks deliver transparent value and direct quality oversight, trading the onyx's delicate nature for its authentic character.
