It really seems like I’ve been the only lucky one to get one of the leather cases and post photos of it (until now, only on Facebook).
I guess it’s from the first batch, which TE decided to call back (if I’m not mistaken).
This German shop (I got it there) still has is some in stock. Don’t know if they ship worldwide, but it seems to have always been the only shop to sell it. First I didn’t believe they really had it in stock, but then I ordered it an got it two days later.
