These charger plates are great for formal events like receptions and banquets. To use them, simply place them under your regular dinner plates. When you're done, clean them by washing under hot running water. Remember, don't put them in the microwave or dishwasher as they're not suitable for these. The sale only includes the charger plates, so other decorative items are not part of the deal. They're made of durable acrylic plastic, BPA-free and non-toxic, so you can use them again and again.
