The Blue Bamboo Wave Shape Sauce Dish (1607BB) is part of Thunder Group's Blue Bamboo Collection. This elegant Asian-influenced collection provides the perfect presentation pieces. This collection can fit all dining occasions. Each piece in the Blue Bamboo Collection is made of melamine, a durable, break-resistant, non-toxic and heat-resistant plastic. Melamine can withstand temperatures from 32°F to 220°F (0°C to 120°C). Melamine is non-microwaveable, but is dishwasher safe (highly recommended for low temperature, top rack only). When placed facing down onto a table, a well-crafted melamine dish remains straight and flat, without a gap between the table and the rim.
