These charger plates are great for formal events. To use them, simply place them under your regular dinner plates. When you're done, clean them by rinsing under hot water. Don't put them in the microwave or dishwasher as they're not suitable for these appliances. Keep them in a dry place when not in use. And remember, the sale is only for the charger plates, so you'll need to get other decorative items separately if you want a more elaborate setup.
