I just use boring zip ties that I mark with a sharpie to make them unique (and show if they&#x27;ve been replaced).  I&#x27;ll also toss a handful of unmarked ties onto the &quot;top&quot; of the luggage.<p>I&#x27;ve occasionally sent a piece of luggage through, and found it re-zip-tied with a new tie, with a TSA love note inside.
