Contrary to what most people believe that their luggages are secured with TSA approved locks when they travel from the US to other countries or within, their luggages are often at risks of losing the locks after TSA inspection. Our special design Lock Safe is engineered to help TSA agents resecure your bags after inspection, and also help you instantly know whether your bags are inspected and opened with Open Alert. Instead of resetting it using a pen or paperclip, our proprietary design allows only you to reset it with your own combination. So your bags are highly secured throughout the trip. You can enjoy your travel with real peace of mind.
