The container is great for foods that can't leak. The description says airtight but that's not true. Day one the container leaked inside of my bag and created a huge mess. Customer service basically said "it's your fault for buying this, it isn't leak proof or airtight". The description literally says airtight. Requested a refund and haven't even heard back from customer service a week later. This experience has all but guaranteed that I'll stay away from Corelle brands in the future. Hopefully others have better experiences!
