Calphalon Premier Space Saving Cookware securely stacks to save 30% more space during storage over traditional cookware sets. This brings a level of tidiness and organization to the kitchen not yet seen in the cookware market. The pans feature a long stainless-steel handle that remains cool while cooking on the stovetop. The stainless steel cookware features a heavy-gauge aluminum core that quickly and evenly distributes heat. The three-layer nonstick interior of the hard-anodized cookware easily releases foods without using extra oil.
