Our Bi-Fold Wallets are characterized by having a single spine fold from where the wallet closes or folds. ID Window Flaps, removable card cases, or extra credit card flaps are often not considered a Tri-Fold because the wallet still folds bi-sectional. Bi-Fold wallets are often the most popular wallets, and we have many ranging in different styles and occasions, such as our vertical upright wallet designed for front pocket or our bi-fold spring tension money clip wallet designed to hold a sufficient amount of cash but also keep your ID and credit cards handy. Our wallets are highly practical and functional, as well as elegantly stylish.
