Troubleshooting
Food is not staying hot for as long as expected
Ensure you pre-heat the jar with boiling water for 3-5 minutes before adding your food to warm the stainless steel walls.
Lid is difficult to unscrew
Avoid over-tightening the lid. If stuck, run the lid under warm water to expand the material slightly, then attempt to grip and turn.
Liquid leaking from the top
Check that the integrated gasket is free of food debris and is properly seated against the rim of the jar before closing.

Setup, Compatibility & Care
To ensure the longevity of your soup jar, always hand-wash the unit with a mild dish detergent and a soft sponge. Avoid using abrasive scrubbers that might scratch the stainless steel surface. Because the stopper and gasket are integrated, ensure the lid is screwed on firmly but not over-tightened to prevent potential issues with opening the container later. Keep the jar in an upright position when carrying it in a bag to ensure the seal remains secure and to prevent accidental leaks.
