It's easy to seal in freshness and flavor with the MaxVac® Vacuum Sealer 3 Piece Canister Set. Vacuum sealing canisters remove air to keep food fresher longer and are perfect for vacuum packaging pressure sensitive foods or liquids such as tomatoes, soups, salad, or fruits. Ideal for storing dry goods, crackers, and cereal to prevent staleness. They are even great for marinating meat. This 3-piece set includes 2-cup, 3-cup, and 4-cup canisters, giving you flexibility for storing smaller and larger portions. The lids have a unique one-way valve design that vacuums an airtight seal with just a few pumps, and the visible green Airlock™ indicator confirms a strong vacuum. Hand pump is included. The canisters can also be used in conjunction with a vacuum sealer with an external port using an external hose attachment (sold separately).
