Superb Canning Lids - Regular Mouth Mason Jar Lids - Baker’s Dozen/Bulk Package of 156 Lids - Made in the USA

Engineered to be the highest quality lids available, these regular mouth canning lids have a specially formulated adhesive that is thicker and wider to seal on virtually all regular mouth mason style jars. BluSeal Integrity offers more sealing power designed to prevent buckling, making these jar lids safe to use with high pressure canners. Look for the blue seal! The distinctive "pop" feature provides an audible and visual assurance of seal integrity. Made with five layers of corrosion protection. It is important not to over-tighten for a proper seal. We recommend tightening with three fingers to ensure the right tightness. Locally USA made in Ohio by a family who has been canning for five generations and is committed to serving your family's canning needs.
