To use these plates, simply take one out of the pack and place your appetizer or salad on it. They are great for special events like weddings and banquets. After use, since they are disposable, you can just throw them away. Remember, do not put these plates in the microwave or dishwasher as they are not safe for such use. There's no special maintenance required, just keep them in a dry place until you're ready to use them.
