Stop oven messes with silicone Spill Guards. These baking bands go around the lip of either a pie or casserole dish and prevent your food from flowing over the top of your cookware and making a mess of your oven. No more splatters or drips. The flexible silicone bands are dishwasher safe and FDA food-grade approved. The pie plate band measures 9 1/2″ x 9 1/2″, while the casserole band is 13″ x 9″.
