This product matches as near as possible the original Jamie Oliver Dinner Sets when produced by Royal Worcester. The difference is minor and measured in millimetres on items such as the bowls and the handle on the mugs is slightly different. Jamie Oliver is one of our favourite celebrity chefs and is hands on when it comes to new china product development. The Jamie Oliver White on White dinner service is made of high quality porcelain and is both practical for everyday kitchen crockery use and to be used as dinner party tableware.
