Mrs. Anderson's Adjustable Silicone Pie Crust Shield keeps pie crusts from burning and over browning. No more burnt edges. It allows pies to rise in the center and reduces spillage from the edges. Neater and more convenient and economical than wadding up aluminum foil. Perfectly baked pies with golden-brown crusts couldn't be easier. With 4-adjustable pieces, the fit is easily customized per pie crust, up to 10-inches.
