Press down firmly and use the vacuum function to remove air from the jar, creating an airtight seal. Store the sealed jar in a cool, dry place or in the refrigerator as appropriate for the contents. To open, release the vacuum seal by lifting the tab or pressing the release mechanism before removing the sealer. Wash the sealer with warm soapy water between uses.

Frequently Asked Questions

What jar sizes does this sealer fit?
This sealer is designed for standard mason jars. Check the jar opening diameter against the sealer dimensions (20×13.5cm base) before purchasing to confirm compatibility with your specific jars.

Does it work for canning or heat processing?
This sealer is designed for dry storage and refrigerator use, not for heat-processing or traditional water bath canning. It is not a substitute for proper canning lids used in high-temperature preservation.

Is it dishwasher safe?
Hand washing with warm soapy water is recommended to preserve the silicone gasket and maintain a reliable seal. Dishwasher use may degrade the silicone over time.

How long does the vacuum seal last?
The seal duration depends on the jar condition, contents, and storage environment. For best results, check the seal before each use and re-seal if needed.

How long does delivery take?
Delivery timelines depend on your location and the shipping method selected at checkout. Estimated delivery times are shown on the product and checkout pages.
