2pcs Pack Regular Mouth Mason Jar Flip Cap Lids with Handle for Ball Mason Jar, Leak-free and Airtight, Compatible with Ball & Kerr Mason Jars (Jars Not Included)

These fit and work well. Don't seem to leak. Only thing I would complain about is that the handle is a little flexible. Not as sturdy as I hoped, but still works as intended so far. Have only had a couple weeks.

Initially they were hard to get on.. but after that they are fine, no leaks and work well

These were hard to screw on my 16oz mason jars- it was very hard to get the threading to match and tighten which cause my jars to leak a little bit when pouring. This was pretty sad because I was putting breast milk! The putting spot is also very hard to open once you’ve closed it all the way

Fit perfectly and work great

Little hard to start on the bottles I had but worked as intended

fits my old blue canning jars perfectly

It is very hard to get these screwed on correctly. I wanted to put canned milk in it. If not quite right they leak in the fridge

The lids leak and are hard to to place in the proper position
