Finally, I can easily accommodate a 1kg coffee beans (without shaking o. Palpitations) and a wooden scoop in it has also space. This box looks good and high quality of (feels like to) and the twist lock engages without effort a. Since this is made of plastic and not gummed, this probably should not be completely airtight. Since keep us 1kg 10-14 days is not a problem, but maybe not quite optimal for longer periods. Only this there is a deduction of points - otherwise I can recommend this can and would get me again. The price for this is OK
