This Thunder rice bowl is made of melamine, which has become a popular tableware material due to its hardness, break resistance and durability. Melamine-based dinnerware comes in place when china or glass cant resist to the extreme conditions of a busy restaurant. With its exceptional whiteness, bright background colors and sophisticated Asian patterns with logograms, this bowl is a real competition to any costly porcelain product. Indeed, it will serve you best in the long run! Please note that non-toxic melamine tableware is dishwasher safe (low temperature setting recommended) and can be used at up to 212 °F, however, heating your foods to higher temperatures in a microwave oven should only be done on microwave safe cookware.
