Not much to say about the quality of the product. It is reasonably well finished. The pen is not used much because it is more specific with your fingers in the end. But with this cover, almost doubling the thickness of the phone and you end up with a smartphone that does not really sense. In addition as the phone is already robust naked, the interest of the case is questionable. So I dropped the bag and only put a screen protector and it is much more convenient and attractive.
