Having a 3 ounce container that I can refill with my shower gel is rather nice considering airline security requirements nowadays. What's cool is that the container is pretty sturdy and feels thick, so I'm not really worried about it breaking/splitting or making a mess in my 1 quart bag.

The interesting thing is the ID label around the cap, so I'm able to determine what liquid is in each. In practice, I'm not sure how helpful that would be if I've only got two or three of these (because they are expensive!) so I'm not going to have lots of these.

Overall I feel confident that this won't break on adventures around the globe - but it IS pricey. If you can find it on sale - then get it, but if you want to save money there are better options.
