The Stop and Lock Luggage Scale from Travelon allows for a simple affordable solution to eliminate pre-trip packing guesswork and hefty overweight luggage fees. This easy to use luggage scale has a patented stop and lock feature. Two hands track the weight of the bag and the second hand stops and locks at that weight so you can set the suitcase down to read the dial. It also includes a tape measure to also ensure bags are not oversized. Take it with you on your trip to ensure you don't tip the scales on your way back.
