The Mr. Lentz Minimal Leather Wallet might be the thinnest bi-fold leather wallet ever made. Which is impressive in its own right. But pair that with the fact that this high-quality wallet was made in America entirely with sustainable materials, like the included non-toxic leather conditioner and vegetable-tanned leather, and this durable piece of carry is all the more impressive. Slim enough to fit comfortably in your front pocket, and tough enough to last a lifetime.
