As Seen in Wired Magazine! RFID Blocking Compact Bi-Fold Wallet by Stewart/Stand

You might never guess from their silky feel that these wallets are made of a stainless-steel thread used in aerospace & medicine!

Ultra-thin & ultra-durable, they also block RFID scanning on your cards to prevent identity theft.

Brown leather exterior with stainless steel interior. Super strong stainless steel feels like silk & is 3 times thinner than paper! Although durable and resistant to corrosive materials such as salts, acids and seawater, Stewart/Stand wallets feel like silk to the touch.
