This 11-piece set has all the essentials for a well-equipped kitchen. The hard-anodized cooking surface is tougher than stainless steel and highly wear-resistant. The aluminum core heats quickly and spreads heat evenly. The Quantanium nonstick cooking surface makes the pieces easy to clean while the riveted handles stay cool. Tight-fitting tempered-glass lids seal in moisture and nutrients for healthier, more flavorful results, while tapered rims allow for easy pouring. Lifetime warranty.
