High-Quality Material -- Our coffee storage canisters are made of 304 stainless steel, which has good rust and corrosion resistance. The silicone gasket and latch between the lid and the container ensure a stronger seal, keeping the flavor and aroma of the coffee beans intact. Innovative Valve -- The stylish coffee canister features a one-way exhaust valve, which can automatically release the carbon dioxide produced by the coffee beans in the canister, and at the same time isolate the oxygen and water vapor outside the canister, keeping your coffee fresh. Freshness Tracking -- There is a date tracker on the surface of the airtight stainless steel coffee maker, which allows you to track the date when the coffee beans were first stored to ensure their freshness through the date wheel, providing you with coffee at the first time and reducing waste. And the included spoon helps you easily control portion sizes for more precise brewing. Wide Range of Uses -- The 1.8L airtight coffee canister is suitable for storing various foods, such as coffee beans, coffee powder, flour, tea, grains, cocoa, nuts, spices, candy, etc., an ideal food saver for home or travel. Stylish Coffee Container -- This coffee canister with a sealed lid has a matte black appearance, with a simulated retro wood grain lid (not real wood), which is very aesthetic. This not only solves the problem of coffee storage but also highlights your noble quality of life.
