Weird Question: Is it possible to buy the disposable cups and plates used in restaurants?

[JP350]

Hi all, I have a granddaughter who were throwing a birthday party for and she loves Disney World, and one of the highlights of her trip every year is eating on those special disney designed paper plates and cups. (I attached the pictures of the ones she likes) Would it be possible to buy these cups and plates online, or in the Disney parks/hotels. Any help you guys have is greatly appreciated.
