- Can these jars be used for pressure canning?
- No. The lids are airtight storage lids, not two-piece canning lids, and are not rated for pressure or water-bath canning. Use them for dry goods, cold brew and fridge storage instead.
- Are the lids really airtight?
- They seal well for dry pantry goods and fridge storage. Some owners report the gasket weakens after many washes, so check the seal and replace the lid if it loosens.
- How much do the jars hold?
- Each jar holds 64 fl oz, or half a gallon. That is about a 5 lb bag of flour or roughly eight cups of liquid.
- Are they dishwasher safe?
- The glass jars generally handle the dishwasher. Hand wash the lids to keep the gasket and seal in good shape.
- What can I store in them?
- Flour, rice, cereal, pasta, coffee beans, cold brew, infused water and bulk leftovers. They are not ideal for long-term liquid storage because the lids are not leak-proof for tipping.
- How do they compare with Ball or Kerr jars?
- They cost less for the size and come as a set, but Ball and Kerr jars have standardized two-piece lids that are canning-safe and easy to replace. Choose these for storage, those for canning.
