Please refer to the following web information. ______________________________ {Product Specifications} Matsunaga Seisakusho Material: Steel with silicone coating Pre-baking: Not required Inner dimensions (approx.): 79 x 53 x 29mm Outer dimensions (approx.): 300 x 218mm Country of manufacture: Japan {Notes before purchase} [About the metal mold manufacturing process (pressing process) and silicone coating] Metal molds inevitably have machine scratches and abrasions due to the force used during molding, such as pressing and bending. Silicone coating is a resin coating applied at high temperatures, so these machine scratches and abrasions are also penetrated. The lines and patterns visible on the mold are a result of this process. The surface roughness is also due to scratches from the metal mold manufacturing process and does not affect the mold release effect of the silicone coating, so please rest assured. Also, returns and cancellations for these reasons are not accepted. {Product Description} [About Bronze Steel Silicone] It is a bronze color close to gold, giving a luxurious feel that replaces gold. This color is not a paint but a color created by heat treatment, so it will not transfer to the baked goods. It uses pure steel with a surface finish that allows silicone to adhere well, and the silicone is applied thickly, making the silicone coating long-lasting.
