Mrs. Anderson's Pie Crust Shield allows pies to rise, reduces spillage, and prevents pie crusts from burning or over browning. Made from aluminum; strong and durable; fits 9.5-inch and 10-inch pie plates. Easily bake frozen and homemade pies without burnt crusts; great for blind baking empty pie crusts, too. Easy to use and stays in place. Fits baking dishes with fluted edges and carrying handles; dishwasher safe for easy clean-up.
