Peace of mind is key to successful travels. This is why we created the Travel Sentry Approved Combination Lock Set. Elegant and sturdy with durable cast zinc construction, it secures your belongings with style. And due to its special code, which is used by several security agencies, this lock can be opened and closed again by airport security without having to call out your name. In return, the inspection indicator shows you that your luggage has been looked at. Its the details that make the difference.
