A simple and effective protection for the Rainbow. Envelope perfectly protects the phone and also asked if the front side facing down (the plastic "excess" willingly a millimeter forward). Flexible, holding well in hand thanks to its texture and relief, good protection for the price. Only downside: the goshawks cutting micro-USB port for charging is a little "just": returning the tip of the charger, it takes a little on the Protection and slightly off the protective film on my screen. I had to slightly enlarge the opening to solve this problem.
