Travelon Anti-Theft Classic Backpack 2, Purple, One Size;

A simple way to secure your bag and still allow for TSA inspection is with these Secure-A-Bag Cable Ties. Each package contains 60 assorted color cable ties and two security friendly clippers. If the TSA opens your suitcase to inspect it, they will replace it with a new cable tie of their own. You will know that your suitcase has been opened before you leave the airport and can file any claims for missing or damaged belongings.
