TSA key lock. A unique patented lock that allows for quick identification as soon as the suitcase is received from the luggage conveyor. If the bag/suitcase is checked, there is a button at the top of the suitcase and it rises as soon as the suitcase/bag is opened and only the original key holder can lower the button back to its original position. The TSA mechanism is a universal mechanism approved in most airports in the world, so if you need to open the lock at the airport, you don't break it like a regular lock, but open it with a special key that is only available at the airport. Suitable for locking a suitcase, bag, locker and anything else. A strong, high-quality mechanism that is easy to operate. Comes in bright colors that help quickly identify the suitcase.
