Reusable Snap Fit Seals by County Line Kitchen for Ball Plastic Mason Jar Lids, Will Not Fall Out, Wide Mouth

I recently received my seals for the plastic lids. I have been impressed with how well they work. They make the plastic lids leak proof and are much better than the metal lids for everyday usage.

These are awesome do not buy any others I did initially & they were garbage - leaked all over & did not fit properly. These are AWESOME!!! Leak proof & fit snugly. So happy I finally found the right ones. I had a problem with pantry moths but not anymore. Highly recommend!!!

I really like being able to seal my quart and 1/2 gallon jars that I use for pantry storage. No worries about raisins, dates, and brown sugar hardening. These do fit both the Ball and Walmart/Mainstays plastic lids and I've had no problem with them falling out.

I wish they were a little thinner, you don't get as many threads from the caps for really secure tightening, especially the white plastic caps but they work ok. They still fall out of the caps at times too

I ordered these to use in my RV. So far I've only tested them at the house, by putting liquid in the jar & shacking it vigorously to check for leaks. So far the seals are awesome, I would recommend them to anyone. The true test will be in the RV fridge on bumpy roads, but I expect them to perform perfectly based on my home tests.
