This is a TSA lock made by TUMI. A TSA lock is a special lock approved by the TSA (Transportation Security Administration). It allows TSA agents to open and relock your luggage for inspection without damaging the lock or the bag, so you can check your bag with the lock engaged. There are some minor scratches on the hook from several uses, but the lock itself has no scratches. * The lock combination can be changed. Simply press the reset button on the bottom of the lock with a thin object like the tip of a ballpoint pen while setting your desired combination. It is currently reset to "0-0-0".
