Review (4/5): They Work Fine
These work ok but they are knock offs of the "real thing". The contents labels are permanent, the cap does not twist to change as my "real" once so, and they do not provide stickers to cover/change the printed word. What if I don't want my soap in that one? Aside from that, they are sturdy and have not leaked when flying. The cap is a little hard to open, but that's ok, no worry it is going to open accidentally. It is nice that they are color coded and of varying sizes, help remember what is really in the tube. Knowing what I know, I would still probably buy them again, mainly because they have not popped open under air pressure, as some containers do. You could write on them with permanent marker as to what the contents are, but I hate to mar them so I use different colored products to help identify.
