Corelle Tree Bird Serving Bowl is the unique Tableware that was introduced in the USA in 1970, and quickly became one of America’s leading brands of everyday dinnerware sets. Corelle’s durability is due to its unique sandwich construction which bonds together three layers of a unique glass material called Vitrelle. Corelle crockery sets are also designed for easy handling and compact storage. For kitchens with limited storage, it nests neatly and efficiently. The designs are therefore long lasting and will not fade, even after years of use.
