Hm, interesting. That second auction states that they're actually not real leather. Here's a snippet from the description.
Made of Bonded Leather (at least 90% real leather mixed with synthetic leather for smooth texture and durability)
I have a sneaking feeling that the other ones are the same.
Oh well. It's still a great cover. The price is terrific, and it looks and feels real to me
, so I'm not complaining.
