The Ultimate Cooking Surface – A world’s first: Black Cube™ combines all the benefits of stainless steel and nonstick cookware. Imagine a nonstick fry pan that is safe for use with metal utensils and can brown like a stainless steel fry pan! Stainless Nonstick is a raised stainless steel pattern over a recessed layer of nonstick coating. This allows for browning on stainless steel without sticking and protects the nonstick coating when using metal utensils. Black Cube™ is built to last with its 3-ply construction and the high quality PFOA free nonstick layer. All pans work on any cooktop and are oven safe up to 500° F. For ultimate convenience they are also dishwasher safe.
