Product Details 　　One sheet of high-quality Japanese black iron plate (JIS standard) 　　Plate thickness: 9mm, Weight: 9 kg 　　Size: 40cm diameter 　　Cut with a laser, so it's clean. Product Description The iron plate has heat retention properties, so the thicker it is, the more slowly you can cook. Heat is evenly distributed, so there are fewer unevenly cooked spots, and you can make crepes. Quite popular. I've sold dozens of these, and there hasn't been a single complaint. Material costs have increased, and this is the limit. In fact, it might go up a bit more in the future.
