These charger plates are great for making your dinner parties look amazing. To use them, simply place them under your regular dinner plates. For cleaning, just rinse them under hot water. Since they're not microwave or dishwasher - friendly, avoid using these appliances on them. They're disposable, so you can throw them away after use if you want. They're made of durable and non - toxic plastic, so they're safe for food. Keep them away from sharp objects to avoid scratches. They pair nicely with our placemats, so consider using them together for a more coordinated look.
