This Casa Vieja Lodge Silicone Phone Wallet is a favorite of our Captains and clients. Backed with 3M tape simply peel and stick to the back of your phone or phone case and you will have a slim wallet to carry your credit cards, ID, and cash. It's expandable, snug, and doesn't slide on surfaces. The grip of the silicone prevents your cards from falling out! Amazing new product that you must try!
