Product Testing: We have tested these jars with both of the following and had no leakage: unlined plastic mason jar lids and one piece metal lids. We put colored water in these and tested upside down and tipped for several hours and had zero leakage. It was easy to slip the liners in the lids, they did not fall out, and they were easy to screw on the jars.
