This is really class! Needless to measure (let's dig into the hull). The attachment clips to the top is a bit confusing (no magnet) but it is very reliable. The only small question I ask myself is about the join between the two parts (hull and above) ... It's two small leather straps rather thin and I hope that eventually they will not break. BUT .... it really is a beautiful case that is the difference compared with conventional covers and cases. I do not regret this purchase.
