True: oxygen makes coffee stale and robs your brew of its full potential. Also true: you very much can prevent that from happening. This vacuum-seal container uses a unique twisting pump mechanism to banish air, moisture, and odors, which stops your beans from aging out before you’ve enjoyed the whole bag. It's made from durable borosilicate glass, and can hold up to 16 oz of raw beans (or anything else you'd like to stow in there), with a vaccuum-lock indicator and a simple release button for ease of use.
