I ordered the envelope described here by Moodie and a shell of Mumbi Amazon. They cost almost the same amount; the protective cover of Moodie costs 5 cents wengier, practically the same price. The shell of Mumbi not only looks totally "cheap" from, they do not fit properly. At the margins (edges) the shell is now and it looks poorly. In the two pictures you can see quite clearly that the protective sheath of Moodie is simply the noble envelope. Also fits perfectly and is not from.
So strong buy recommendation for the shell of Moodie!
