taco eater :
seymours from Philadelphia, PA United States
bought two of these and filled one herbal essence shampoo and the other with conditioner....unfortunately its 4oz so they flagged me going through airport security, remember the 3-1-1 rule for all carry-ons.
3-1-1 for carry-ons = 3.4 ounce (100ml) bottle or less (by volume) ; 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger placed in screening bin. One-quart bag per person limits the total liquid volume each traveler can bring. 3.4 ounce (100ml) container size is a security measure.
when i came back i used it for oil in case i run out of gas and the cap never leaks when i keep it in my pocket, thats why i gave it 5 tacos
