Keep coffee beansand moreperfectly fresh with this clever canister. Pleasing curves in glass and black conceal several mechanisms that ensure freshness. An airtight silicone seal keeps out odors, moisture and other impurities that might affect the flavor of coffee, loose-leaf tea or spices. With just a few twists of the lid, an integrated vacuum pump removes air to prevent oxidation. An understated indicator reveals itself when the vacuum lock is sealed properly, and a simple button releases the vacuum when it's time to brew. Topped with its matte black lid, the medium glass canister looks modern on your open shelves or coffee station.
