The transparent, airtight Fellow Atmos is a vacuum container for coffee beans that prevents oxidation and extends the shelf life of coffee by up to 50%.
Its huge advantage over other vacuum containers is the integrated pump. Just twist the lid back and forth to remove the air. As soon as a green ring appears on the top, a vacuum environment has been created.
To reopen the can, just press the button on the top part, this will let air into the container and you can easily open the container again.
