Japanese-made stainless steel pot set, versatile with 4 sizes. - Brand: Wahei Freiz - Model Name: EM-032 - Material: Stainless steel - Set Contents: 4 pots, 2 handles - Sizes: 14cm, 16cm, 18cm, 20cm Thank you for viewing. This item is new and has not been taken out of the box. I am selling it because I accidentally purchased it. It seems like the pots can be used with a steamer for steaming food. Of course, they can also be used as regular pots. It also appears to be compatible with IH cooktops.
