Two out of the three items are new and unused, but have been stored at home for a long time. One item has been used a little and then stored at home for a long time. The lid is slightly torn. There is also some dirt. I don't know if the new and unused items have any dirt from long-term home storage. I don't know the details, but I think it's aluminum, but I'm not sure. The container in the second photo has two lids. Please only purchase if you understand that these items have been stored at home for a long time. Please refrain from purchasing if you are sensitive to these issues.
