What it does

  • A low-poly shape with wide facets, so you can grip it with bare hands
  • Sized to fit regular mouth Mason canning jars you already own
  • Works as a cover for dry goods, opened canned goods, and freezer storage
  • Printed in plastic and made to order in the USA after you order

Round out your pantry with a lid shaped for regular mouth Mason canning jars. You twist it onto the jar rim to close up dry goods, leftover canned food, or items headed for the freezer.

The lid has a low-poly top with flat facets instead of a smooth dome. This shape gives your hand more surface to hold onto when you turn it onto the jar. The design was based on measurements from standard plastic storage caps sold for Mason jars, so it is shaped to fit regular mouth jars specifically.

This is a plain lid on its own, not a full jar or ring band. It is made to order in the USA once you place your order.

What it is made of

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
