I purchased this last week at Majimaya Kashi Doguten. I only realized it was a deep mold right before I started working, so I reluctantly bought a replacement and am now selling this one. It is unused. Product information is as follows: {Product Specifications} Brand: Matsunaga Seisakusho Material: Steel with silicone coating Pre-baking: Not required Inner dimensions (approx.): 80 (62) x 45 (30) x H20mm Outer dimensions (approx.): 300 x 218mm Country of manufacture: Japan {Notes before purchase} [Regarding the metal mold manufacturing process (pressing process) and silicone coating] Metal molds inevitably have machine scratches and abrasions due to the strong force used during molding, such as pressing and bending. Silicone coating is applied with heat, so these machine scratches and abrasions are also penetrated. The lines and patterns visible on the mold are a result of this processing. 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. {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 paint but is achieved through 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.
