Wide Mouth Fermentation Lid - Tough Tops

This is a Mason Tops Tough Top lid with a hole and grommet to accommodate an airlock. Includes a silicone ring gasket to seal. Unlike other plastic storage lids that bend and buckle, Tough Tops are built to last. The underside of each lid has a custom gasket channel which holds the BPA-free gasket in place at all times - no more wondering if a tight seal has actually been made or struggling to keep your gasket in place. Airlock not included.
