The French Bifold Wallet is one inch taller than the Standard American, measuring 4 ¼ x 4 inches, folded. It still fits comfortably in the back pocket. The advantage is: 4 more card pockets (total of 10) and a deeper, double bill pocket for larger foreign currency. You can store more in the slip pockets behind the cards.
Our American leather is buttery soft making it very comfortable, but it is not delicate. My wallet is designed to last for years, typically outlasting commercial wallets.
