Brand New in unopened/sealed retail box. Brand: Viking Model: 13-Piece Tri-Ply Cookware Set CopperRenowned for its professional-grade residential stoves and appliances, Viking presents its 13-piece Tri-Ply Copper Cookware Set. Offering superior performance and durability, the tri-ply design combines an attractive mirror-finished stainless-steel exterior, aluminum-alloy core for heat conductivity and high-quality 18/8 stainless-steel interior. The even transfer of heat from the tri-ply design of stainless-steel exterior bonded to a layer of aluminum alloy and then finished with a final layer of high quality 18/8 surgical-grade stainless-steel gives you more efficient “rim-to-rim” cooking. The interior aluminum layer also reduces hot spots across the bottom of the pan, allowing you to deliver the perfect sear. Because the clad construction helps to increase the efficiency of each pan, you can cook at lower temperatures and achieve the same results as cooking on single-ply pans at higher heat, thus saving energy. The construction offers even heat distribution for more efficient cooking. The ergonomic handles reduce pressure on your wrists and ensure a comfortable grip. Vented, tempered glass lids help prevent boil-overs and allow you to monitor progress without losing heat. The stainless-steel interiors and exteriors are easy to clean and non-reactive, so the cookware doesn’t impact the flavors of your dish.
