Superb design produces superb results.

Fed up with failed seals? Looking for mason jars made in U.S.A.? See what happens when a company of engineers uses modern design to fix home canning.

We made it better

An innovation in food preservation.

For years, there have been few improvements to home canning products. And the quality of once-trusted brands has declined. When our Amish country community couldn't find a reliable source of mason jar lids, they turned to us for a solution.

As a company known for engineering precision metal parts, we naturally saw ways to bring innovation to canning. We started by developing a lid with a more reliable seal, better quality assurance, and stronger corrosion resistance.

We then set out to equip canners across the country with durable, American-made mason jars that perform season after season. Our high-quality glass is specially formulated for greater clarity, durability, strength-to-weight ratio, and thermal shock performance.

Today, we’re improving canning for the next generation by returning to a simple idea: that doing it right is better than doing it over.

Read below to see the superb difference.

MAKE EVERY BATCH SUPERB

Canning lids you can rely on.

You don’t compromise when it comes to putting food on the table. And neither do we. As canners ourselves, we know that failed seals can ruin many hours of hard work. See how we designed a better lid to preserve your harvest and your peace of mind.

AMERICAN-MADE MASON JARS

The difference is clear.

Superb canning jars are manufactured in the U.S.A. from sustainably-harvested (not mined) renewable materials. Every jar undergoes an extensive quality check, so you can give your family your best.

Durable, American Glass

Our glass is formulated to produce stronger, lighter, and clearer jars. And when we say Made in the U.S.A., we mean it. Every jar. Every lid. Every time.

Thermal Shock Protection

Tests have shown that our high-performance materials better hold up to the heat. That means fewer breaks, less waste, and no worries.

20 Point Quality Check

Our jars undergo a high-tech inspection throughout every stage of production. Advanced tools such as radar and laser scanners detect and eliminate defects.
