Circular Onyx Cufflinks

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.

Swivel back

Swivel back folds flat, locks with 90° rotation, one-handed.

Why this is supported

The swivel back's operation is described:

Where whale-back closures demand a straight lever for insertion and then a controlled bend into a clasp—often needing two hands—the swivel back simply rotates on a single hinge, so the lock action is faster and can be felt without looking, rewarding less experienced users.How swivel backs compare for everyday fastening — swivel_back_vs_whale_back

Another source notes that

The hinged arm folds flat against the post so the cufflink passes through standard dress-shirt buttonholes without catching, and once inserted a 90-degree rotation locks it perpendicular to the post—a motion that can be completed with one hand, unlike toggle backs that require threading the bar through the hole.How swivel backs compare for everyday fastening — swivel_back_folding_action
