I am the traveler who sometimes cleans out my small, used containers and refills them to use for trips so I have a mini version of what I use at home. But lately I have just packed the large containers and that does take up precious cargo space. If you travel as much as Josh, this is a useful find! It’s effortless, expensive, but makes packing so easy. It is also a great way to try out new brands.  And some great brands have put together useful travel kits at 3Floz.com. Check out Pangea, Hauschka and other organic brands.
