Incor Incor This product is compatible with IH cooktops. Incor features a multi-core, 5-layer construction that combines three types of special steel plates (stainless steel, carbon steel, and solid aluminum) using unique technology. The bottom, which is directly exposed to heat, is made of solid aluminum, which has the best thermal conductivity, quickly absorbing heat. The central carbon steel evenly distributes the temperature to the bottom, sides, and lid, and the surface is made of the highest-grade stainless steel with special manufacturing. All items are unused and stored. ^_^ If you have any questions, please ask in the comments. ^_^ Similar to Royal Queen pots, it has a 5-layer structure with carbon in between, and is designed with a thick bottom of 6.8cm, focusing on bottom pressure. ^_^ I am selling it at a low price because I don't use it.
