Classic dinnerware like this is popular in Parisian bistros and brasseries. Made of fully-glazed porcelain, the pieces are larger and heavier than standard tableware and are sturdy enough to go under the broiler. The pattern has a blue fillet border. Microwavable and dishwasher safe. 13-oz. mugs (4" high), set of four. Made in Japan. A Williams-Sonoma exclusive.
