So I bought this Harmony Monterey, not because I needed one but because it was in a Batwing case, which I did need:

Well, although it arrived in totally inadequate packaging, the mandolin didn't seem to be damaged. But the case! Stitching has pulled out in several areas and it's just falling apart.

I returned it. Seller didn't even wait to receive it before relisting. Still no info in the ad about the condition of the case. So in the event that you too were thinking of buying this for the case, don't bother.
