we have these nice sturdy medium sized freezer bags. i throw the stuff in them and leave it. it is my travel pack. like the sturdy. has about 3 bottles and shave stuff in it. it is about 25% full. went through dfw, and tsa pulled the bag and said it was too big. gave me one of their idea of a 1 ltr bag. mine measures about 10"x10"(25x25 cm).
same line, they wanted to throw my hair color away because they could not read size on the label.
same line, some woman(from Sweden) had purchased half a dozen hand lotions. they were 4 oz each. the sweetheart from tsa did allow that the person could go back and check the bottles.
