Review (2/5): Pass on these unless you want a rigid container with a super tiny opening.
These get a 2-star, because they partially worked. The lid for the one I filled with shampoo became impossible to open, so I just had to unscrew the cap. I got these because I don't like the silicone travel bottles. These are much more rigid, but are practically unsqueezable. For this price, get something else.
Pros:-Anything watery will probably work fine
-Rigid if you're looking for that
Cons:-Silicone lube leaked out of the container on the plane
-Shampoo container cap became impossible to open
-Lid openings are super tiny and so are the cap openings. Loading anything into it is a pain
-Expensive for a tiny piece of plastic
