These serving trays are very easy to use. Just place your food on them and you're ready to serve at your wedding, banquet, or other event. Remember, these trays are not microwave or dishwasher safe. To keep them in good condition, store them in a dry place. If there's a small spill, you can wipe it off with a damp cloth. Since they are disposable, you don't have to worry about extensive cleaning after use.
