The canister is drawn stainless steel, not molded plastic, so there's no draft angle on the sidewalls; this means you can push the plunger-style lid down into the canister to the level of the coffee, forcing all of the oxygen out through a valve in the lid. Once you've reached maximum depth, you then flip the handle to seal the valve. It's essentially as close as you can get to vacuum-packing the darn thing.
There's also a second aesthetic lid you can use to cap the top.
The Airscape Coffee Canister Classic comes in nine colors and two sizes, 10 oz. ($24.80) and 1 lb ($36).
