Review (5/5): Had all the features I needed...plus more
Admittedly, I have not used them yet. My air travel is in a few weeks. I read the information for all the travel options on Amazon before picking these. My reasons were: the triple leak protection on the caps, the squeezable body of the bottles, they were all the 3 oz. size (read the product details carefully. Some may seem cheaper until you realize they are small bottles), can either be hung or affixed to a wall due to their design, and came with their own plastic bag.
