Are those lids warrantied against mice.
I’m out in the country and mice in winter are a constant battle.
I’d write the company about any warranty, I have no idea. They are hard plastic with a red rubber ring. I think if I were worried about mice, I would put rings back on the jars after checking the seal once they cooled.
Do I ever hate mice. Just finished a huge ordeal with cleaning out my parent’s home in the U.P. and the mice made awful messes. Ruined things that my mother had saved for over 50 years.
