What is the purpose of clear TSA approved toiletry bags in different sizes?
TSA approved toiletry bags are designed to meet the airline's 3-1-1 rule for storing liquids, gels, and aerosols in carry-on luggage. They are made of clear plastic so they can easily be seen by TSA personnel when passing through a security checkpoint. The different sizes allow travelers to choose the right bag for their needs, such as a small bag for a few essential items or a larger bag to store all of their toiletries.
