These air tight canisters are perfect for storing roasted coffee beans, powder and tea leaves. Made from food grade stainless steel they won't rust, and feature a silicone ring lid to lock in freshness. A date recording ring is in inbuilt on the lid to record the canning date of tea leaves or roasting date of coffee beans. Rotate the dial to adjust the month, and rotate the rubber ring outside the disk to adjust the date.

Coffee beans will continuously release carbon dioxide after roasting, and the cover is equipped with a one-way exhaust valve which will automatically discharge the carbon dioxide produced by the coffee beans in the tank, and at the same time isolate the oxygen and water vapor outside the tank to keep the coffee beans fresh.

Perfect for the home, office or coffee shop.
