Not just for use on cakes - use them when you bake brownies, bars or even casseroles. Helps prevent over-cooking and drying out around the edges of the pan! Bake perfectly level, moist cakes. Avoid high-rise centers, cracked tops, or crusty edges. Strips are 1-1/2" wide. Set contains 2-30" bands, enough for two 8" or 9" pans.
