The Kilo is a coffee and food storage canister. Made with galvanized steel and coated with a food-safe matte painted finish, so your stored goods remain fresh. Airscape technology features a patented plunger lid designed to fit snugly against the inside of the canisters. 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. This Airscape holds a whole kilogram of coffee beans, or re-fill it with other food items such as flour, brown sugar, granola, oats, and popcorn kernels.
