I decant some of my toiletries into these little bottles. It takes a little finessing to get the cap screwed on properly though. After you put the white circular piece in it, you may have a hard time screwing it onto the bottle - it's like a screw that's losing its thread. I found that it's easier if you don't push the cap down too hard. Once the cap is on correctly, it does stay on. No leakage so far on multiple plane trips.
