Reusable Wide Mouth Canning Lid w/ Ring and Rubber Grommet

Our reusable wide-mouthed canning lid is perfect for any fermentations you have going at home, from kombucha to sauerkraut to kimchi. We drilled a hole in the lid and put in a rubber grommet, perfect for an airlock. 

Using an airlock allows any pressure developed during fermentation to escape without allowing bugs, air, or other things that can harm whatever you are fermenting into your mason jar. 

This BPA-free, reusable plastic lid works with any wide-mouth (2.75") mason jar and comes with a lid ring to ensure a good seal with the jar.
