Using these serving trays is super easy. Just place your desserts or food on them and set them up at your event. They're disposable, so you don't have to worry about cleaning up. However, keep in mind that they're not safe for the microwave or dishwasher. Since they're made of paper cardboard, don't expose them to too much moisture. And remember, these trays are non - returnable and non - refundable, so choose carefully. They're great for special events like weddings and banquets, adding a touch of style to your food presentation.
