Some call it a science, some call it an art. Regardless of how you choose to define it, in the process of wallet making, two elements are absolutely essential — functionality and form. The folks at Feit have brought these two universal principles face to face in the 2012 Spring Hand Sewn Collection. Their Handmade Vertical Wallet ($157) is hand-molded by Florentine artisans from a single piece of vegetable tanned calf skin. The result is a completely seamless, elegant and absurdly practical wallet, intended to slip into the top suit or jacket pocket hassle free. Pre-orders are being taken now, and only 18 will actually be made, so act now if the spirit moves you.
