Described as possibly its "most innovative product" on the company's site, the KILLSPENCER Pocket Card Carrier for iPhone 4 and 4S allows users to safely keep their cards fastened to their phone. The device has a modern look and is made from locally sourced Rosewood. It features a patent-pending Flat Spring Card Lock mechanism which makes sure that your cards are kept secure.
The product was created in the KILLSPENCER workshop in Los Angeles, and can hold up to three cards (your I.D., your debit card, and your credit card.)
The KILLSPENCER Pocket Card Carrier has sure hit the nail on the head. It combines the protective features of many phone cases with the personalized design of other iPhone covers. Not only that, this revolutionary iPhone case can hold all your cards to your phone -- consolidating all your pocket items. After this, you may never need a wallet again.
