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. 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. Even when not in use, the silicone helps make your phone easier to grip and prevents it from sliding on smooth surfaces.
