This case is quite well finished, but the supplied copy sent did not fit for the iPad 4th generation. First, the iPad can only with effort push the envelope and secondly not clip the two inner tabs to the iPad, so there is no protection against falling out when unfolded there.
Conclusion: This is now already the second disappointment on "envelope order fits iPad 4 in Amazon". The shell goes back and now another is purchased in a retail store with "fitting" option.
