They are exactly what you think they are - plain, inexpensive plastic tablecloths. Just be careful not to put objects that are too heavy on it (heavy tray, sharp objects, etc.) as they are flimsy and tear easily. (They can also deflate as they are very thin, so if you use them outdoors or even near an air vent, weigh them down with something.)
