OXO's line of commercial-grade Bakeware provides professional quality, exceptional durability and superior performance. Each pan is constructed with ILAG™ technology, a Swiss-engineered, PTFE, ceramic-reinforced, two-layer, commercial-grade coating that provides the ultimate non-stick food release. This feature makes it resistant to scratches, stains, corrosion and abrasions. The micro-textured pattern ensures even baking by minimizing surface contact and promotin g airflow, and adds structural rigidity to help prevent warping. Visible pan dimension markings on top surface allow for quick and easy size identification.
