This is a Hinoki (Japanese cypress) rice storage container. When you microwave frozen rice in this container, it tastes like freshly cooked rice and has the aroma of Hinoki. It's about the size of one adult rice bowl. I have used it several times. I am organizing my cupboard, so I am selling it. As shown in the fourth image, there is a scratch on the corner. I don't think it affects the use. Therefore, I have lowered the price.
