Keep your cards and cash ultra secure with the beautifully engineered EOS Aluminum Wallet. Made entirely of CNC 6061 aircraft grade aluminum, this wallet is made of two plates secured together by four O-rings as well as durable stainless steel hardware. As you add more cards or cash, the O-rings are able to handle the increase in tension yet maintain its shape and hold. The EOS Aluminum Wallet has a capacity of up to an incredible 25 cards, 20 cards and 20 bills, or a massive 60 bills at a time and you use the specially cut thumb slot to slide each out. No matter how much you’re carrying, the EOS Aluminum Wallet can handle the task. Hidden in the design of this wallet is also a convenient bottle opener.
