Airscape Glass Food Storage Canister - Patented Airtight Lid Preserves Food Freshness, Glass Storage with Bamboo Lid (Medium 7-Inch)

Airscape technology features a patented plunger lid designed to fit snugly against the inside of the canister. As the Airscape lid is pressed down, the oxygen is forced out through a two-way valve. Once the plunger is directly above the contents, flip the handle down to prevent further oxygen exchange & dramatically increase the shelf life of your stored goods.
