Silicone wallet with 3M adhesive sticks to the back of most smart phones. Securely holds up to 3 credit cards, a drivers license or business cards. This item is great to protect against identity theft. It is also good for hotel keys and will not deactivate the strip. Credit cards will be protected from deactivation on phone. Perfect for work, a night on the town, or sporting events, when all you need is a Driver's License and debit, credit card or cash, not your entire wallet or purse.
