Authentic cufflinks from British designer, Katharine Hamnett. Made of brass with silver-colored rhodium plating. Features a beautiful diamond-cut center with a black jet Swarovski crystal. Rare item. New, unused condition, but without packaging. For those who need a dedicated package for gifts, etc., it will be included for an additional 700 yen (see image). Katharine Hamnett's packaging, while understated and casual for jewelry accessories, uses recycled paper and avoids other materials as much as possible, reflecting the brand's environmental protection concept. Thank you for your understanding. If you request it in the comments, I will then adjust the price and create a dedicated listing.
