I was able to find replacement rubber rings at the True Value store in town. I found out that these types of jars have what is called lightening closures. All I know is that I love the way they look as well as how they keep out humidity. Thanks Dr. J!

"I just kicked out the fire and we're on our way!"
Didn't take much convincing!
