We use the finest Napa leather and a stainless steel clasp in LIU LI HUA. The wallet is designed to feel compact and secure in your hand and pocket. The inside of LIU LI HUAis specially designed to make it easy to slide cards out, though the wallet is built to keep the cards securely in place when not in use You'll see other wallets that are clearly designed for just carrying a few cards, but LIU LI HUA is unique that it is designed from the start for both. Many wallets tend to get bloated over time, but LIU LI HUA has a unique internal "skeleton" to make sure your wallet always remains as compact as possible.
