This is an authentic tie clip from the British brand, Katharine Hamnett. It's made of silver-colored rhodium-plated brass and features a stylish design combining playing card suits (diamonds, hearts, clubs, and spades) with Swarovski crystals. This item was designed and supervised by fashion designer Hiromichi Ochiai, who became the creative director in 2016. It's a rare model with limited production, making it difficult to obtain. It's a new, unused item, but it doesn't come with the original packaging. If you need the dedicated packaging for a gift, it's available 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. If you request it in the comments, I will adjust the price and create a dedicated listing.
