Yomarket Mason Jars

Yes, the glass jars are dishwasher safe. However, we recommend hand-washing the metal lids to preserve the integrity of the airtight seal and prevent potential rusting over time.

While these jars are made of durable, food-grade glass, they are primarily designed for pantry storage, spice organization, and refrigerator items like overnight oats. They are not specifically rated for high-heat pressure canning or water bath processing.

The screw-on metal lids create an airtight seal that is excellent for keeping dry goods fresh or storing jams and sauces upright in the fridge. They are secure for standard storage, but we wouldn't recommend tossing them loose in a bag where they might be jostled.

You can place these in the freezer for short-term storage, but proceed with caution. Always leave at least an inch of headspace at the top to allow for expansion, as glass can crack if the contents freeze and expand too rapidly.

These feature a wide-mouth opening, which measures approximately 2.75 inches in diameter. This makes them significantly easier to fill with thicker ingredients like nut butters or overnight oats compared to standard-mouth jars.
