Honestly these are not worth buying. Sorry company  that's selling them. I mean if TSA wants I to your bag there going to get into your bag. I know I know these are TSA approved but seriously you think this lock is going to deter someone from getting  into your suitcase. Better off just not locking your suitcase. I travel all the time and had these on my suitcase and they ended up broken beciase TSA person said couldn't open and sorry we had to break them.  Whatever stuff happens.
