Yesterday we told you about the Mophie Juice Pack Boost. And while the Boost can be a lifesaver, it can be a bit inconvenient to keep track of. That's why you might consider purchasing one of these double decker cases. Initially designed to hold two phones, it is the ideal size to hold a phone and Mophie Boost. The Double Decker can be customized to meet your exact needs. Choose from over two dozen different exterior colors and patterns, from glossy black crocodile (above) to plain brown (below), you can find what suits you best. You can choose the perfect interior color to match. And one of the most useful options is the ability to choose the back cover. There are many options, from leather with metal belt clip to snap-on buttons with belt. However you prefer to carry your phone, there is an option for you. Once you have designed your ideal case, you can personalize it with letter or image stamping. (See below.)  Because this case will be customized just for you, feel free to share any special requests you may have. And don't forget to include the make and model of your phone (and Boost, if you would like) so the case will be a perfect fit!
