The envelope is processed from very soft, matt leather and properly. The Lumia slides in and out very well. Single hull with no frills. It takes the phone by gently holding on to the sides and pressing down or handle from the top to the unit - therefore the recesses on the side above the left and right. Both work well. The shell has no logo, what I find very pleasant. The shipping was very fast and everything went smoothly! A long-term durability, I can not judge, because I use the shell only very briefly.
