With the Veripart TSA combination lock you secure your suitcase against luggage thieves. You can, for example, hang the lock on a lockable zipper. Handy when the case itself does not have a lock. Is the trip going to the United States? The lock has a TSA certification so that customs can check your luggage without breaking the lock. If you do not have a TSA-certified lock, they can cut the lock open or force it.
