You'll never burn your pie crusts again! Rather than working hard to shape aluminum foil around the crust, simply attach this shield to the rim of your pie dish, allowing your pies to cook thoroughly in the middle without overcooking the crust. Made of durable, heavy duty aluminum, this shield is reusable, easy to remove and easy to clean. Fits pies from 8.5in/21.5cm to 9in/23cm wide. Hand washing recommended.
