These are Lanvin cufflinks, imported from France through an authorized dealer (made in Germany). They are made of silver-colored rhodium-plated brass with onyx as a design point. A very popular model, and hard to find. Current department store LANVIN cufflink prices as of 2026: ○ Metallic: ¥31,900 ○ With stone, shell, or Swarovski: ¥42,900 Unused and new, but only the cufflinks themselves are available, without packaging. If you need packaging for a gift, etc., it will be provided for an additional ¥700. I will adjust the price, so please leave a comment (see image).
