Product Details 　　One piece of domestically produced black iron plate (JIS standard) 　　Plate thickness: 9mm, Weight: 9 kg 　　Size: 40cm diameter It's cut with a laser, so it's clean. Product Description Because iron plates have heat retention properties, the thicker they are, the more slowly you can cook. Heat is transferred evenly, so there are fewer unevenly cooked spots, and you can make crepes. It's quite popular. Material costs have increased, and this is the limit. It might even go up a bit more in the future.
