When the envelope arrived, I was happy like a little kid! Looks like real wood, but is none. But it is also not hard plastic. The outside is a little bit pressed, soft. (I do not know how to describe it otherwise ...) The surprise came when I took the envelope from the plastic bag. An acrid, pungent chemical smell! Disgusting. I put the envelope 3 days on the balcony, I could use it. Now if you do not his nose is directly to the shell, you go. So all in all: Cool Case, Pure Chemistry.
