Made from a 4.8 mm thick 7-layer material, it allows for cooking right to the edge, and the pans are designed so that a non-stick coating is no longer necessary. When the pan is hot enough, you only need to reduce the heat by half, and the pan will take care of the rest on its own. Thanks to the surface treatments (Silvinox or Brinox) and the shape, these pans are very easy to clean.
