They work like they should! They do kind of stick together, so just carefully peel them apart, line up with the top of the jar, and then close the lid. Let them sit for a few minutes before trying to open them so they seal properly. I thought they weren't going to work for me at first, but then I let it sit and opened the jar again and they were perfect. I've already purchased another box!
