This is a Corning Corelle Forever Yours oval platter. The platter is 12 1/4" long. It is in very good condition with one small flat chip along the rim. I only see a few utensil marks, barely noticeable. Corning/Corelle produced Forever Yours from 1988-1994. Please see my other items for more in this pattern.
