I bought Le creuset stoneware. When I found it at the Internet shop amazon.co.jp, I suddenly pushed the button to buy it because it was so cute. After receiving it, I read the details of it and found out it could be used in refrigerator, oven, and microwave. It can go from microwave straight to the table. It is not only cute but also easy-to-use. I made steamed sweet potatoes(Kumara Satsumaimo) .
