Luggage accessories are items that can be used to enhance the functionality of a suitcase or bag. Common examples include tags, straps, locks, and packing cubes. Tags are small pieces of paper or plastic that are attached to a piece of luggage to identify its owner. Straps are used to secure the contents of a bag and keep them from shifting during transport. Locks are used to protect the contents of a bag from theft. Packing cubes are small containers that can be used to organize and store items within a suitcase.
