Wide range of caps. Lots of small ones and a few big ones. I only had large jars when I got them so I had a pack of lids that I couldn't use but now I have a lot of small jars and small lids are used now. Fits great. The only negative issue I had was that the middle lids start to curl, making it difficult to apply to the opening of the jar. But after a few seconds of working with these lids, the cat food will close securely with a tight-fitting lid.
