Review on Refillable Cosmetic Container Packaging Essential by Abby Page

Just used these travel bottles for the first time and they are excellent. The double cap design makes them virtually impossible to leak. I carried shampoo, conditioner, liquid facial soap and astringent and not a drop came out for four flights. They're not very soft and "squeezable," but I don't mind since whatever I put in comes out quite easily without squeezing. If this is a problem, you can always remove the inner cap when you're not traveling and then replace it before your trip home for extra leak protection.
