This is a hot plate made by Sugiyama Kinzoku Co., Ltd. The product name is Deep Grill Pan, 50cm deep. After purchase, it was stored in a bag in a dark place without being used at all. I have decided to sell it because I have judged that I will not have the opportunity to use it in the future. The operation has been confirmed, so I would like to ask those who will use it with care to purchase it. Because it is deep, I think it can be used for a wide range of dishes such as okonomiyaki, teppanyaki, yakiniku, and hot pot. However, the instruction manual and box are not included, so please understand. Therefore, the box for shipping will be a commercially available cardboard box. Size: Inner diameter 345mm, Outer diameter 360mm, Depth 50mm Full water capacity: 4.3L Plate material: Aluminum alloy Cord length: 1.4m Thank you for viewing.
