These charger plates are great for formal events like receptions and banquets. To use them, simply place them under your dinner plates. When it's time to clean, wash them under hot running water. Remember, they're not for the microwave or dishwasher. Since they're BPA - free, reusable, and non - toxic, you can use them again and again. Keep them in a dry place to maintain their durability and sturdiness. And don't forget they pair nicely with our placemats to enhance the table setting.
