The Luna Concrete iPhone Skin protects your iPhone with concrete. In fact, what this case does is simple. It encases your iPhone in a concrete case and gives it that sturdy build and an unusual look. However, you must not consider this as a gag. They don’t take your sleek and beautiful iPhone and dip it into freshly poured concrete. As a matter of fact, this is a real slab of concrete. In addition, the design is thin enough to make the cover just as light as any other iPhone cover. Also, the concrete slab resembles the pockmarked lunar surface. This makes the entire design one of a kind. So, if you are willing to give your iPhone an unusual makeover, this case is worth a try.
