collaborated with a luxury leather goods brand to customize hardware snap buttons for high-end wallets. Made of T2 red copper through precision stamping and mirror polishing processes, the surface is as bright as a mirror with a high-end and luxurious texture. The rebound opening and closing design has a crisp sound when pressed, opening and closing smoothly without jamming. The ultra-thin base fits inside the wallet without increasing its thickness. The snap button is tightly engaged to firmly fix the wallet and prevent banknotes from falling. It is suitable for wallets of different sizes, easy to install without traces, helping the partner upgrade the texture of wallet products, increase the price by 30%, and become a iconic accessory for high-end leather goods.
