Debubble tool for canning

These are so awesome. Great for getting the bubbles out of your jars. Actually live saver. They do not scratch the inside of your canning jars. Highly recommend.

Must have for canning!

[This review was collected as part of a promotion.] As someone who has canned since she was little, I have to admit this is a handy little tool. I used to can with my Mamaw and we always guessed at the headspace and used a spoon to get bubbles out but this tool does both. I like the graduated increments which makes it super easy to accurately measure headspace depending on the recipe. I also like that it's long enough to easily reach the bottom of quart jars. It's lightweight but sturdy for thicker recipes and easy to clean. Canning is hard work but this tool makes it so much easier!
