Please read the profile before purchasing. ^_^ These items have been stored on a shelf for a long time. I mainly used them for making New Year's simmered dishes, so they haven't been used much. I no longer use them, so I hope someone can use them when cooking for a large group. The two stainless steel pots in the photos are heavy and sturdy. The aluminum pot is easy to use. The other stainless steel pot is deep. Please take a look at the images to confirm. I've set a low price for purchasing all four items together. The box will also be large. Please refrain from price negotiations as the shipping costs are significant. I am also selling on other sites, so I may suddenly remove the listing. Thank you very much. ^_^
