I am so pleased with this luggage strap.  I used it for both identification and security.  I was concerned about checking the fully loaded Samsonite "Tote-A-Ton" duffel bag that I was using for the first time.  It was filled with baby clothes and gifts.  I didn't know how it would hold up under the rough handling of the airlines.  I was worried that the zipper would break and everything would be scattered all over the place.  I used two of these to go around the outside of the duffel bag to hold everything in place.  It is easily removable so the TSA agents can open up the bag to check the contents, if necessary.  The bag arrived at my destination completely intact.  The bright green against the black duffel made it so easy to identify at the baggage claim.  I plan to use this over and over.
