Not released in Japan. Top-tier series, Copper Core, Sauté Pan, Deep Type. Diameter 28.5cm. 5 layers: Stainless Steel, Aluminum, Copper, Aluminum, Stainless Steel. A disadvantage of stainless steel is that it takes time to heat up, but because it contains copper and aluminum, which have the best thermal conductivity, it heats up quickly. This type of frying pan is not sold in Japan, perhaps because it is difficult to manufacture or is too expensive. It is famous in America as a top-quality cookware brand and is a favorite of many renowned chefs. Currently, it is sold for $350 (approximately ¥55,000). Including shipping from America, it would cost over ¥60,000. The lid has scratches from use (no stains), but the frying pan has only been used a few times and is in beautiful condition with only minor scratches. Price non-negotiable.
