A flexible shell very simple design, the key is there. Flexible material, very pleasant to the touch texture. Small spikes on the sides for a good grip. The screen protection film is of good quality, like many movie it gives a matt appearance on the screen of the iPhone, which is quite a shame. It avoids scratching. We must clean the screen with the small cloth provided for good adhesion of the protective film. The small scraper eliminates bubbles. Small regret, a second film for the back of the iPhone would be welcome there too to prevent scratches on the "apple" and around the photo and flash lenses.
