Thin aluminum. Basic storage of tools and or groceries. Doesn't seem heavy duty

3 dents. One on back, it will not show. One underneath, it will not show. Third on the lid, topside near the dee zee label., and this will show. I know I bought the amazon warehouse for a good price. But it probably should've been labeled as fair condition. And not like new. I can return it but than I'll have to buy a new one for $60 more. Wish I had more discount on a damaged product so I'm debating to return. The dent sits on a piece that can't be pulled because the it doesn't protrude on the underside. It's a multi layer lid.
