Kiril Stefan Alexandrov

Good looking, slim, and functional. That’s the story behind every Big Skinny wallet. Sleek and silky to the touch, the durable nylon micro-fiber shrinks the space needed by a traditional wallet. Its material is at least five times thinner than leather, meaning a Big Skinny is just 1/10 the thickness of a folded leather wallet. Founder Kiril Stefan Alexandrov, based in Cambridge, Massachusetts, spent years searching for the perfect thin wallet and came up empty. He wouldn’t rest until he developed one himself. He tested fabric after fabric—more than 75 combinations—until he found “the one.” Big Skinny’s advanced nylon micro-fiber is durable, looks beautiful, and has a satiny feel. Kiril was inspired by an Italian luxury fashion house, who used a similar fabric for their globally popular tote bags. On top of their aesthetic attributes, Big Skinny wallets are water resistant and machine washable, too. Kiss your bulky billfold goodbye, and your pocket or purse will thank you.
