Review on Refillable Cosmetic Containers with Leakproof Keychain Design by Michelle Ocampo

They are perfect for what I need. I wanted to use some of the cute holders from Bath and Body Works but I hate single use plastics so I wanted them to have reusable containers and fill the bill. They are the same size, so they fit perfectly in the holder. I've been wearing these for a few weeks with no problems. The hinged lids hold up well and refilling is no problem. Some reviewers have mentioned issues with the lids, but I haven't had any issues with them. Just follow the instructions - turn counterclockwise a quarter and pull out - and they work fine, no damage. I only took off one star because the rings that hold the key clips are very flimsy. So if you count on them to hold, you're more likely to lose them sooner rather than later. Personally, it didn't bother me as I took them off as soon as I opened them. If you want to use a clip, I would recommend replacing the original metal rings with something more durable, like a key ring or small jump ring like those used for dog tags.
