TSA-approved clear quart bag - sturdy and surprisingly roomy! [SEP] This clear bag quart bag is terrific for travel, and is surprisingly roomy and sturdy! My family used these during a recent trip to Europe - they zip open and closed easily, are made of heavy plastic, and the gusset design allows one to fit a large amount of travel-sized bottles! Much better than a zip-lock sandwich bag. Highly recommend, especially for anyone who wants to use only carry-on luggage instead of checking their bags.<br /><br />Liquid prescription/OTC medications and other prescription items, such as contact lenses (and lens solution) are generally exempt from the TSA's 3-1-1 liquids rule for liquids, gels, aerosols, creams and pastes (3.4 oz bottle or less; 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger), and can be packed in a separate bag; you just have to pull them out for inspection with your quart-sized bag.
