no suitable large

Dear people,
I had bought this cover for my first Macbook Air 13 ''.
These fits and is very highly recommended.
When my friend a Macbook Air 11 '' was, the decision was easy.
The quality of the cover is perfect, but for the Apple Air 11 '' could be smaller.
It takes in a ladies business handbag too much space. On the part of the seller, I must say a perfect service, he has a second envelope delivered us home free, so we can safely conclude that it really is the smaller model. So I just correct my original review and give full points, as is appropriate for such a service and confidence on the part of sellers, no complaint. It remains only to find out how I can this new envelope return the seller for me.
The pragmatic solution by my girlfriend, she buys from now matching handbags so that the shell has its place, as they will miss neither the Mac nor the envelope. Regards Greg
