Unfortunately, and that would actually have been foreseen in advance, collects on and felt everything so in the micro world who flies so. From Dust on ... to hair. The hair of my cat are attracted apparently by the bag. At least she looks after a short time already from no longer really presentable. This is connected primarily with the fact that the nice warm felt invites make my cat even for naps. However, if I keep my iPad wöllte in cabinet or in a drawer the whole time, I did not need this envelope. The only way I could prevent the problem described.
Cat owners, I would advise against the pocket. Otherwise it is in my opinion a worthwhile purchase!
