The Smart Folder Sider Fibre for iPhone 5 is basically a set of two covers with independent functions. The first is a Ready-to-Use Flip-top Case, which is designed to fit the contour precisely. The open-face approach allows for easy operation. The removable case uses magnetic attachment for added flexibility, making it possible to use it independently or along with the secondary case. For those who like a touch of glam, this one is for you. It comes in the glitzy combination of silver outer cover and black inner hard cover. The second case is a hard shell with a unique integrated stand that allows you to browse the web or watch videos and slideshows with ease. The PC Case is crafted from durable, smooth-to-touch & scratch-resistant materials, making it very alluring. In short with this case you get the added advantage of using them both together or simply one instead of the other.
