Cylindrical Cufflinks

BOSS Cylindrical Cufflinks feature a solid brass core that permits professional re-polishing, though the silver finish restricts deep restoration. Hypoallergenic due to nickel-free brass, the plating resists tarnish when stored in a box and after applying fragrance. The silver variant requires only a soft cloth to restore mirror shine, while brass needs polishing. Fitting standard shirt cuff buttonholes (20 mm face width), these cufflinks offer a refined, durable accessory without specific hypoallergenic certification.

Restorability

Solid brass core permits professional re-polishing, though the silver finish restricts deep restoration.

Why this is supported

The solid brass construction is the foundation of the cufflinks' longevity, allowing professional re-polishing without exposing a base metal.

Because the cufflinks are solid brass rather than plated, they can be professionally re-polished multiple times over their lifespan without fear of wearing through to a base metal, preserving their appearance indefinitely.Brass care and preventing tarnish over time — solid_brass_restorability

However, the silver-tone variant in this product has a tarnish-resistant plating that limits deep restoration:

The silver variant features a tarnish-resistant plating over the brass core, meaning it naturally retains its luster longer and requires only a soft cloth for maintenance, unlike the yellow brass that benefits from periodic polishing.Brass care and preventing tarnish over time — silver_tone_plating_advantage

The polished finish can be maintained at home using a jewelry-grade rouge cloth or a baking soda and lemon juice paste, which restores the mirror shine, but it is also susceptible to tarnish and requires proper storage and avoidance of acids from cologne or perspiration to prevent etching.

The high-polish brass finish develops a patina that can be reversed with a jewelry-grade rouge cloth or a mild paste of baking soda and lemon juice, restoring the original mirror shine without scratching the surface.Brass care and preventing tarnish over time — polished_brass_maintenance

Regular storage in the included designer box minimizes humidity exposure, and wiping dry after wear prevents chemical damage, reducing the need for professional restoration.
