A kitchen staple, this 13"x15" baking pan is ideal for large batches of cookies or for sheet cake baking. Part of the OXO family of BPA free commercial grade bakeware, this Pro series has professional quality and performance, along with exceptional durability. Each pan is constructed with ILAG™ technology. This means using a PTFE, ceramic reinforced, 2 layer commercial-grade coating to ensure non-stick food release. That's a long way to say these surfaces are resistant to scratching, wearing, stains and corrosion. The micro-textured surface also ensures even baking as there is minimal food contact with the pan and good airflow. Dishwasher safe.
