Travel security is more important than ever. This cable lock is small enough to tuck into your pocket and flexible enough to go through tough-to-lock spaces. That's right, it's both small and mighty! And it's a Travel Sentry Certified lock which means Transportation Security Administration (TSA) baggage screeners can open it up without damaing your bag or lock. And that's good news... Nothing like peace of mind, knowing your bag (or lock) won't be abused in the inspection process.
