Really useful luggage identifier

A friend of ours travels often with us around the world. She has a black item of luggage similar to everybody else that we heave off the airport carousel for her only to find it isn't hers! Now she has these fab luggage straps, she knows who she is and can identify her luggage quickly and easily. What a joy and really useful present for her and less sore arms for us. Large and clear lettering too!
