Unfortunately, the case for an iPad Smart Cover not used is too large, it slips inside from one to the other side and the extra fabric bulges downright. Because she will not reveal to me the sense of double protection through the simultaneous use of a Smart Cover and your pocket, it goes back to Amazon.
Out of interest I tried the iPad Smart Cover with a friend - it fits perfectly and the bulge above is shelved. Everything fits perfectly and precisely.
Conclusion: If someone is planning the simultaneous use of SC and this envelope, accesses. All others should look for other cases. 4 of 5 stars because the quality is good and it is pointed in the description on the SC-suitability.
