We have featured several practical iPhone 4 cases with back slots for cash and credit cards. But apparently the following Elasty iPhone 4 case with multi functional elastic bands is more practical and handy.
The amazing iPhone 4 case is named Elasty, and designed by Yoori Koo. As we can see from the images, Elasty is a form fitted protective case with snap-on design, and comes with vibrant color. Similar with most of iPhone 4 cases, the custom cutouts allow you access all iPhone 4 buttons and functions, but most importantly, Elasty features 5 multiple functional elastic bands at the back, which can not only hold your cash and credit cards like a card slot, but also hold your headphones, stylus and more. Undoubtedly the elastic bands are more useful than that integrated card slot. Unfortunately Elasty is a design concept at present, but the concept iPhone 4 case has won the Korean Belkin Design Awards. We believe the practical protective case should be able to become reality soon.
