When carrying it, it was deformed when dropping the lid. It is weak to shock only on aluminum.
After extracting the soup, it had to be banned as it would change its quality for a whole day or more. Is the metal chemically changed? I was slightly bad, so I immediately moved it to another container.
Also, before using it, put the green vegetables and simmer for more than 10 minutes, it was when the inside surface did not turn dark.
I would like this to be done before shipping from a user-friendly standpoint.
I guess the stainless steel was better.
