Mrs. Anderson's Silicone pie crust shield prevents pie crusts from burning or over browning, while allowing pies to rise in the center and reduce spillage. Made from 100% European grade silicone. It is stronger, more flexible, and more durable, allowing it to maintain it's shape and non-stick quality through many uses. Designed to fit a 9.5-10 inch pie plate. Freezer and Oven safe (-90 to 570-degress Fahrenheit). Microwave and dishwasher safe.
