Use the Eagle Creek 3-Dial TSA Lock & Cable to connect multiple suitcases and travel bags. Or to attach your luggage to an object. So you reduce the chance that one of your bags will be whisked away unnoticed. The steel wire is 128 cm long and flexible. Of course you can also choose to only use the lock for your suitcase. Then it is nice to know that he is TSA certified. This allows Customs to open your suitcase in case of an inspection in the USA without forcing the lock.
