Our ultra-slim Wallet designs solve the top 5 wallet problems. Our Big Skinny wallets are ultra-thin, flat, and small because we use our proprietary ultra-thin (but sturdy) nylon micro-fiber wallet material which does all the work separating your cards and cash rather than thick leather like regular wallets. Each of our thin wallets are designed to organize and fit all of your plastic cards, cash and everything else without having to give up any card or cash pockets, or forcing you to use unconventional wallet designs. With our wallets, you don't give up any functionality nor do you have to leave any of our stuff at home--our wallets look like regular wallets but they perform 50% better. We make your wallet thinner by actually making an ultra-thin wallet that fits everything you have yet decreases final wallet size by 50% or more depending on which of our 40+ wallet designs you choose. When you swap your layers of thick leather for our skinny nylon, your wallet goes on a diet but all your stuff stays the same because our skinny layers do all the work coupled with our novel design elements.
