Dramatically increase the shelflife of your coffee with Airscape Coffee Bean Canister - available in three sizes (250g, 500g, and 1KG) 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 coffee.
