Have the envelope received today. This is offered in several variants to several prizes from several manufacturers here. This was the cheapest. Basically, it does not differ from the more expensive variant that I had for my Macbook Air, however, depend on the material her thin and does not fit as accurately as it did, the model for the Air. Too Bad. But for the price should not complain, functionally they served their purpose, even if the material is not felt, but a plastic mat that looks like felt and therefore much cheaper than, for example, the 5 euro more expensive model of EasyAcc.
