This is the business card case woven from flexible stainless steel fabric, with a hand as smooth as silk and a strength that surpasses leather. Using 25,000 stainless steel threads that are three times thinner than a piece of paper--.001"--this business case is no thicker than a wallet, fitting unobtrusively in a front pocket. Impervious to stretching and resistant to corrosive salts and acids, the stainless steel is the same metal fabric used in architecture and aerospace applications for its unsurpassed durability. Despite its durability, the case's tightly woven steel fibers and leather-trimmed interior is smooth to the touch. The steel also passively resists radio-frequency hacking--the latest identity theft technique that attempts to scan newer credit cards. It holds up to 50 business cards and two credit cards; with an identification window.
