These serving trays are super easy to use. Just place your food on them and present them at your event. They're perfect for weddings, banquets, and other fancy parties. When it comes to maintenance, since they're disposable, you don't need to do much. Just throw them away after use. But remember, they're not safe for the microwave or dishwasher, so don't try to clean them that way. Keep them in a dry place when not in use to ensure they stay in good condition.
