Great for making large batches of cookies at one time. Professional non-coated bakeware with unique, natural non-stick properties due to its pebble pattern, allow for airflow under baked goods for more even browning and quick release. Made of premium heavy gauge, recyclable aluminum with strengthened handle areas and rolled, beaded and/or coined edges to prevent warping. Hand wash promptly in hot soapy water (avoid detergents with a chlorine base).
