Dish holders are items used to hold dishes, such as plates, bowls, and cups. They come in a variety of shapes and sizes, and can be made from materials such as plastic, metal, or wood. The term 'dish holders' can also refer to trays, which are flat surfaces with raised edges that can be used to carry multiple dishes at once. Trays are often used in restaurants and catering services to transport food from the kitchen to the dining area.
