Yes, it was in sealed, opaque, container -- in fact, there were two of them in that container.
I plead guilty to knowing that the TSA could open it. In fact, that was the purpose in buying the lock.
I might have looked more closely and saw how flimsy the cable was, but I didn't.
I really had no way of knowing that the combination of the lock could be reset by someone who didn't know it, when it was locked, until I got curious and tried doing it.
