Product name: ママレンジ (Mama Renji)
(1) It's a 1970s-vintage Japanese toy stove called MamaRenji for ages 5 and up. It cooks with actual heat.
(2) This toy stove is only for making pancakes. I tried to cook another menu with it. It can't adjust the heat.
(3) It is edible. I ate it after filming. It tastes good.
(4) It was discontinued. The manufacturer went bankrupt long ago. I bought it at an auction. (Contract price: 4500 yen)
