GHP Fiber and Plastic Dinnerware Plates Yellow Set of 4. This is a very pretty set of fiber and plastic blend Melamine style dinnerware. The plates are unique with a muted yellow color. The rims are ribbed and the finish is glossy. There are utensil marks, but these are disguised well because of the color. The plates are 10.25”. The diameter of each may not be identical to one another due to the molds that were used. This variation in size is not noticeable unless the plates are stacked. Thank you for looking.
